摘要

Abstract Homoallyl and bishomoallyl alcohols with a disubstituted double bond treated with ethylmagnesium bromide in the presence of titanium (IV) isopropoxide are converted into the products of a reductive ethylation of the olefin fragment. Under similar conditions esters of β, γ-unsaturated carboxylic acids undergo a successive cyclopropanation of the ester group and reductive ethylation of the double carbon-carbon bond and yield 1-(3-ethylalkyl ...
