This invention relates to substituted cyclooctenes of formula (I), wherein X and R are defined in the specification.

Chromium(II) Reduction of Trichloromethyl Carbinols and their Corresponding Ethers: One-step Synthesis of Z-Vinyl Chlorides

Secondary trichloromethyl carbinols and their corresponding ethers can be reduced by chemically or electrochemically generated chromium(II) chloride to form Z-monochlorovinyl compounds in one step.In the presence of a carboxy function in the α-position an E-double bond is formed.Tertiary cabinols favour the formation of dichlorovinyl compounds and rearranged carbonyl compounds.Product ratios can be altered drastically by a change in the reaction conditions; this sheds light on the reaction mechanism.

Regiospecific Synthesis of β, γ-Unsaturated Ketones from Allylic Alcohols. Claisen Rearrangement of α-Allyloxy Ketone Enol Derivatives

β,γ-Unsaturated ketones are prepared with regiospecific C-C bond formation at the former γ-position of primary, secondary, or tertiary allylic alcohol precursors by a process involving sigmatropic Claisen rearrangement of intermediate α-allyloxy ket
