NUCLEOPHILIC SUBSTITUTION OF α-ALLENIC ALCOHOLS VIA THE MURAHASHI METHOD: 1,3-DIENES SYNTHESIS.
Fan, Changlie,Cazes, Bernard
, p. 1701 - 1704 (2007/10/02)
The alkylation of α-allenic alcohols 1 by the Murahashi procedure leads to 1,3-dienes 4.This process allows the direct nucleophilic substitution of labile or hindered α-allenic alcohols by organolithium reagents.
