Origins of the substituent effects in the aldol condensation of axially chiral thiohydantoins: a computational study.

Aldol reactions are one of the most fundamental organic reactions involving the formation of carbon-carbon bonds that are commonly used in the synthesis of complex molecules through the condensation of an enol or enolate with a carbonyl group. The aldol reaction of thiohydantoin derivatives with benzaldehyde starts with hydrogen removal from C5 by lithium diisopropylamide (LDA) to form the enolate. Benzaldehyde adds to the enolate either at the less or more hindered site.
