Robert Edward Corbett (13 June 1923 – 3 February 2018) was a New Zealand organic chemist. He is noted for his contribution to natural product chemistry through the isolation and structural elucidation of compounds from New Zealand native plants.

Early life and education

Born on 13 June 1923, [1] Corbett was the son of Walter Corbett and Margaret Whitehead Corbett (née Robertson). He studied at the University of Otago, graduating Master of Science with first-class honours in chemistry in 1945. [2] Corbett later undertook doctoral studies at the University of Cambridge under Alexander Todd on the structures of some of the metabolites—puberulic acid, puberulonic acid, and stipitatic acid—of Penicillium species. [3] He showed that they contain the tropolone skeleton, [3] and his PhD thesis, titled The structure of certain antibiotics was completed in 1950. [4]

In 1949, Corbett married Enid Mary Carter in Cambridge, England, [5] and they went on to have two children. [6] [7]

Academic and research career

In 1945, Corbett was appointed as a lecturer in chemistry at Otago. [8] After returning from Cambridge in 1950, [3] Corbett rose to become a professor in 1966, and the Mellor Professor of Chemistry in 1972. [8] [9] When he retired in 1983, he was accorded the title of professor emeritus. [8]

Corbett's research at Otago was primarily concerned with the study and structural elucidation of essential oils isolated from New Zealand native plants by steam distillation. Under his supervision in 1970, doctoral student Denis Lauren first isolated the diterpene compound from the rimu tree ( Dacrydium cupressinum ) that came to be known as laurenene. [10] [11] [12] Corbett also investigated extractives from barks, leaves, heartwoods and lichens, and determined the structures of many new, and derivatives of known, di-, tri- and sesquiterpenoids. [3] He also studied the synthesis and rearrangement of some of the compounds that his team isolated. [3]

Later life and death

In retirement, the Corbetts lived in Tauranga. Enid Corbett died there in 2012, [7] and Ted Corbett died on 3 February 2018, also in Tauranga. [6]

Honours and awards

In 1972, Corbett was elected a Fellow of the Royal Society of New Zealand. [13] He was also a Fellow of the New Zealand Institute of Chemistry. [8]

<i>Dacrydium cupressinum</i> Species of evergreen tree

Dacrydium cupressinum, commonly known as rimu, is a large evergreen coniferous tree endemic to the forests of New Zealand. It is a member of the southern conifer group, the podocarps. The former name "red pine" has fallen out of common use.

Diterpenes are a class of chemical compounds composed of four isoprene units, often with the molecular formula C20H32. They are biosynthesized by plants, animals and fungi via the HMG-CoA reductase pathway, with geranylgeranyl pyrophosphate being a primary intermediate. Diterpenes form the basis for biologically important compounds such as retinol, retinal, and phytol. They are known to be antimicrobial and antiinflammatory.

Carminic acid Chemical compound

Carminic acid (C22H20O13) is a red glucosidal hydroxyanthrapurin that occurs naturally in some scale insects, such as the cochineal, Armenian cochineal, and Polish cochineal. The insects produce the acid as a deterrent to predators. An aluminum salt of carminic acid is the coloring agent in carmine, a pigment. Natives of Peru had been producing cochineal dyes for textiles since at least 700 CE. Synonyms are C.I. 75470 and C.I. Natural Red 4.

An isocyanide is an organic compound with the functional group -N≡C. It is the isomer of the related nitrile (-C≡N), hence the prefix is isocyano. The organic fragment is connected to the isocyanide group through the nitrogen atom, not via the carbon. They are used as building blocks for the synthesis of other compounds.

Lake Matheson Lake in New Zealand

Lake Matheson is a small glacial lake in South Westland, New Zealand, near the township of Fox Glacier. It was a traditional food-gathering place for local Māori. An easy walking track circles the lake, which is famous for its reflected views of Aoraki / Mount Cook and Mount Tasman.

Fenestrane Chemical compound with four carbon rings sharing a single carbon atom

A fenestrane in organic chemistry is a type of chemical compound with a central quaternary carbon atom which serves as a common vertex for four fused carbocycles. They can be regarded as spiro compounds twice over. Because of their inherent strain and instability, fenestranes are of theoretical interest to chemists. The name—proposed in 1972 by Vlasios Georgian and Martin Saltzman—is derived from the Latin word for window, fenestra. Georgian had intended that "fenestrane" solely referred to [4.4.4.4]fenestrane, whose skeletal structure looks like windows, and Kenneth B. Wiberg called that specific structure "windowpane". The term fenestrane has since become generalized to refer to the whole class of molecules that have various other ring-sizes. Georgian recommended rosettane for the class, based on the structural appearance as a rosette of flowers.

Lewis Norman Mander,, FAA, FRS was a New Zealand-born Australian organic chemist. He has widely explored the synthesis and chemistry of the gibberellin class of diterpenes over a 20-year period at the Australian National University (ANU). In particular, he studied the effect of these hormones on stem growth and on the reasons why plant undergo bolting during plant development. The July 2004 edition of the Australian Journal of Chemistry was dedicated to Mander on the occasion of his 65th birthday. He retired in 2002 but remained active at the ANU until 2014. In 2018 Mander was made a Companion in the General Division in the Order of Australia which "...is awarded for eminent achievement and merit of the highest degree in service to Australia or humanity at large". In an interview he gave after winning his award, Mander said that his goal was to improve the efficiency of extracting food from plants with the possibility of reducing food shortages in the future.

Alan R. Battersby English organic chemist

Sir Alan Rushton Battersby was an English organic chemist best known for his work to define the chemical intermediates in the biosynthetic pathway to vitamin B12 and the reaction mechanisms of the enzymes involved. His research group was also notable for its synthesis of radiolabelled precursors to study alkaloid biosynthesis and the stereochemistry of enzymic reactions. He won numerous awards including the Royal Medal in 1984 and the Copley Medal in 2000. He was knighted in the 1992 New Year Honours. Battersby died in February 2018 at the age of 92.

Labdane Chemical compound

Labdane is a natural bicyclic diterpene. It forms the structural core for a wide variety of natural products collectively known as labdanes or labdane diterpenes. The labdanes were so named because the first members of the class were originally obtained from labdanum, a resin derived from the gum rockrose.

In chemical nomenclature, a preferred IUPAC name (PIN) is a unique name, assigned to a chemical substance and preferred among the possible names generated by IUPAC nomenclature. The "preferred IUPAC nomenclature" provides a set of rules for choosing between multiple possibilities in situations where it is important to decide on a unique name. It is intended for use in legal and regulatory situations.

Arthur Smithells British chemist

Arthur Smithells, CMG FRS was a British chemist. Born in Bury, Lancashire, on 24 May 1860. His father James Smithells, was a railway manager. He was educated at University of Glasgow, then spent time under Roscoe and Schorlemmer at Owens College, Manchester. He gained his B.Sc. from the University of London, then took supplemental courses at Munich and, with Robert Bunsen, at Heidelberg University. In 1883 he was appointed assistant lecturer at Owens College, and two years later succeeded Professor Sir Edward Thorpe as Professor of Chemistry in Yorkshire College, Leeds, which was subsequently incorporated as the University of Leeds. Smithells went on to hold the position of Pro-Vice-Chancellor at Leeds, which he held until he retired from the Chair then becoming Emeritus Professor in 1923. During his career he was Honorary Educational Adviser on Home Science and Household Economics to King's College London, President of the Society of British Gas Industries (1911).
