摘要

A simple general route for the conversion of olefins to gem-disilylcyclopropanes, involving the dichlorocyclopropanation of the double bond followed by silylation using the Me3SiCl/Li/THF reagent at 0–10°, is described. Acetylation of bicyclic derivatives thus obtained constitutes an original synthesis of cycloalkylidene ketones by a process more convenient than those previously used, and also provides new acetyl dihydrofurans.
