1-Ethynylcyclohexanol (ECX) is an alkynyl alcohol derivative which is both a synthetic precursor to, and an active metabolite of the tranquilizer ethinamate, and has similar sedative, anticonvulsant and muscle relaxant effects. It has been sold as a designer drug, first being identified in the UK in March 2012. [1] [2] [3] [4]
Chemical formula Synonyms CAS number C 10 H 16 N 2 O 8: Ethylenediaminetetraacetic acid (EDTA): 6381–92–6 C 12 H 22 O 11: sucrose: 57–50–1 C 18 H 29 O 3 S: sodium dodecyl benzenesulfonate: 2155–30–0
Ethinamate (1-ethynylcyclohexanone carbamate) is synthesized by combining acetylene with cyclohexanone to make 1-ethynylcyclohexanol, and then transforming this into a carbamate by the subsequent reaction with phosgene, and later with ammonia. Some lithium metal or similar is used to make the acetylene react with the cyclohexanone in the first ...
Similarly, an acid can be used in the place of an alcohol to form the anhydride, although dicyclohexylcarbodiimide is a more typical reagent. The equilibrium can be shifted in the favor of the anhydride by utilizing an acid in a 2:1 ratio that forms an insoluble salt with the imidazole. Typical acids are trifluoro- and trichloroacetic acids ...
1-Hexanol (IUPAC name hexan-1-ol) is an organic alcohol with a six-carbon chain and a condensed structural formula of CH 3 (CH 2) 5 OH. This colorless liquid is slightly soluble in water, but miscible with diethyl ether and ethanol .
However, reaction pathways in which dimer or other oligomers are the reactive species have also been discovered, [24] and for lithium amides such as LDA, dimer-based reactions are common. [25] A series of solution kinetics studies of LDA-mediated reactions suggest that lower aggregates of enolates do not necessarily lead to higher reactivity. [17]
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O.Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.
Several routes exist for the production of cyclohexenone. For the laboratory scale, it can be produced from resorcinol via 1,3-cyclohexanedione. [6] Cyclohexenone is obtained by Birch reduction of anisole followed by acid hydrolysis. It can be obtained from cyclohexanone by α-bromination followed by treatment with base.
