Abstract

Abstract Pd (PPh 3) 4-catalyzed intramolecular selenocarbamoylation of allenes led to the regioselective formation of α, β-unsaturated five-and six-membered lactams having an allyl selenide unit. This procedure could be applied to the synthesis of the corresponding sulfur analogue by thiocarbamoylation as well as a cyclopentenone.(© Wiley-VCH Verlag GmbH & Co.
