Abstract
(Chemical Equation Presented) Alternatives with silicon: The enantioselective Lewis acid catalyzed addition of racemic silyloxyallenes to aldehydes is reported. A {(salen)CrIII} complex efficiently catalyzes the reaction of these α-acylvinyl anion equivalents (see scheme) with excellent enantioselectivity, high yield, and superb control over the configuration of the resulting double bond.
