✦ Synopsis


Recently, allyltrimethylsilane has been shown to be a good reagent for allylation of acyl halides 1 or carbonyl compounds 2 in the presence of Lewis acid. Now we wish to report here a new and convenient route to cyclopentene derivatives using the reactions of 3-trimethylsilylcyclopentene-1, a cyclic allylsilane, with various carbonyl compounds. 3-TMS-cyclopentene-1 is a useful new reagent for the regiospecific introduction of cyclopentene skeleton in organic synthesis, which can easily be prepared by the hydrosilylation of cyclopentadiene.
