Pd-CATALYZED ALLYLIC ALKYLATION OF PYRROLES WITH ALLYL ALCOHOLS PROMOTED BY TRIETHYLBORANEt

摘要

Triethylborane promotes the Pd-catalyzed allylic alkylation of pyrroles with a variety of allylic alcohols to provide either C2 allylation products(alpha,alpha,gamma,gamma-dimethylallyl alcohol and geraniol)or C2,C5 diallylation products(allyl alcohol,alpha-,beta-,gamma-methyl-,and alpha-,gamma-phenylkllyl alcohols)in good to excellent yields under mild conditions.
