摘要: Abstract Treated with boron trifluoride etherate in dioxan solution, methyl 12,13-epoxyoleate gives the 12- and 13-oxo-oleates as major products. These are accompanied by cyclopropane compounds (8–11%) which mainly cis trans isomers of 9,10-methylene-12-oxo-heptadecanoate [1-(7′-carbomethoxyheptyl), 2-(2′-oxoheptyl)cyclopropane]. In benzene solution cyclopropanes formed higher yield (38%). The structure long-chain esters can be determined oxidation chromic acid.
