Allylic alkylation with function-bearing organozinc reagents
Doucet, Henri,Brown, John M.
, p. 995 - 1000 (2007/10/03)
The first palladium-catalysed alkylations of allylic acetates with organozinc reagents bearing functionality are reported.The reaction proceeds well from ethanoate, and propanoates, derived organozinc halides and provides a useful method for transferring these moieties to an allyl fragment.The reaction proceeds through a monophosphine complex; attempts to perform asymmetric syntheses are unsuccessful so far. - Keywords: palladium; coupling; allylic substitution
