A mild,
one-pot procedure to produce 3-substituted allylic alcohols
from α,β-unsaturated ketones is described. The addition
of an organolithium nucleophile produces a tertiary allylic alcohol
as an intermediate, which undergoes a 1,3-OH-migration assisted by
FeCl
2
. The proposed mechanism indicates that a
syn
-facial migration occurs for the major product. Yields
as high as 98% for the one-pot reaction are reported.
