A new camphor-based N-propionyloxazolidinethione provides remarkable levels of asymmetric induction for both chelation- and non-chelation-controlled aldol processes. While the aldol condensation of the derived di-n-butylboryl enolate with various aldehyde

The aldol reactions from boron enolate derived from camphor-based N-propionyloxazolidone exhibit exceptionally high stereoselection.The initial aldol adducts from lithium mediated reactions equilibrate to furnish erythro isomers.Erythro selection is contr
