The ene reaction is a chemical reaction between an alkene with an allylic hydrogen and a compound containing a multiple bond, in order to form a new σ-bond with migration of the ene double bond and 1,5 hydrogen shift. The product is a substituted alkene with the double bond shifted to the allylic position.
The Sekani language or Tse’khene is a Northern Athabaskan language spoken by the Sekani people of north-central British Columbia, Canada.
In organic chemistry, hexene is a hydrocarbon with the chemical formula C6H12. The prefix "hex" is derived from the fact that there are 6 carbon atoms in the molecule, while the "-ene" suffix denotes that there is an alkene present—two carbon atoms are connected via a double bond. There are several isomers of hexene, depending on the position and geometry of the double bond in the chain. One of the most common industrially useful isomers is 1-hexene, an alpha-olefin. Hexene is used as a comonomer in the production of polyethylene.
But-2-ene is an acyclic alkene with four carbon atoms. It is the simplest alkene exhibiting cis/trans-isomerism ; that is, it exists as two geometric isomers cis-but-2-ene ( -but-2-ene) and trans-but-2-ene ( -but-2-ene).
Androstenediol, or 5-androstenediol, also known as androst-5-ene-3β,17β-diol, is an endogenous weak androgen and estrogen steroid hormone and intermediate in the biosynthesis of testosterone from dehydroepiandrosterone (DHEA). It is closely related to androstenedione (androst-4-ene-3,17-dione).
EcoHomes was an environmental rating scheme for homes in the United Kingdom. It was the domestic version of the Building Research Establishment's Environmental Assessment Method BREEAM, which could also be applied to a variety of non-residential buildings. It was replaced by the Code for Sustainable Homes in April 2008.

1-Androstenedione, or 5α-androst-1-ene-3,17-dione, also known as 4,5α-dihydro-δ1-4-androstenedione, is a synthetic androgen and anabolic steroid. It is a 5α-reduced isomer of the endogenous steroid 4-androstenedione and acts as an androgen prohormone of 1-testosterone (4,5α-dihydro-δ1-testosterone), a derivative of dihydrotestosterone (DHT).

In organic chemistry, the Myers allene synthesis is a chemical reaction that converts a propargyl alcohol into an allene by way of an arenesulfonylhydrazine as a key intermediate. This name reaction is one of two discovered by Andrew Myers that are named after him; both this reaction and the Myers deoxygenation reaction involve the same type of intermediate.

In organic chemistry, the Conia-ene reaction is an intramolecular cyclization reaction between an enolizable carbonyl such as an ester or ketone and an alkyne or alkene, giving a cyclic product with a new carbon-carbon bond. As initially reported by J. M. Conia and P. Le Perchec, the Conia-ene reaction is a heteroatom analog of the ene reaction that uses an enol as the ene component. Like other pericyclic reactions, the original Conia-ene reaction required high temperatures to proceed, limiting its wider application. However, subsequent improvements, particularly in metal catalysis, have led to significant expansion of reaction scope. Consequently, various forms of the Conia-ene reaction have been employed in the synthesis of complex molecules and natural products.
