Abstract

A facile double allylation/ring-closing metathesis/Claisen rearrangement route for preparing vinylcyclopropanes 6 is developed. The efficient synthesis includes O-allylation of α-allyl-α-sulfonylketones 8 with allylic bromides, ring-closing metathesis of diallyl compounds 9 and sequential Claisen rearrangement of the resulting oxepines.
