Expeditious formation of γ-lactones upon palladium-catalyzed double nucleophilic addition of bis(TMS)ketene acetals to vicinal allylacetates
摘要:
Polysubstituted gamma-lactones are easily obtained, in one step, upon the interaction of bis(TMS)ketene acetals with vicinal allylic acetates in the presence of catalytic amounts of Pd(PPh3)(4). (C) 2008 Elsevier Ltd. All rights reserved.
