Reactions of (trialkylsilyl)vinylketenes with lithium ynolates: a new benzannulation strategy.
(Trialkylsilyl)vinylketenes react with lithium ynolates to produce highly substituted phenols in a new benzannulation strategy that proceeds via the 6pi electrocyclization of an intermediate 3-(oxido)dienylketene. [reaction: see text]
