Abstract
Abstract Methyl- and ethyl-vinylketene 3 were added to several simple olefins 1 to afford alkylated 2-vinylcyclobutanones 4 , which in turn rearranged to cyclopentenones 6 (via dienones 5A , B ) or 7 (via 1,2-acyl migration) under acid catalysis. Evidence is presented for a cyclopropyl-carbinyl intermediate 8 .
