title: Synthesis of highly substituted cyclopentenones via the [4 + 1] cycloaddition of nucleophilic carbenes and vinyl ketenes.
abstract: [reaction: see text] Vinyl ketenes have been shown to undergo [4 + 1] cycloaddition with a variety of nucleophilic carbenes to deliver highly substituted cyclopentenones as products.
