摘要：

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 controlled by the choice of the enolate counterion.
