Abstract

In the presence of potassium cyanide or the potassium cyanide/18-crown-6 complex as a cocatalyst, 1-2 mol% of titanium(salen) complex 1 catalyses the asymmetric addition of achiral cyanoformates to aldehydes, giving cyanohydrin carbonates with high enantiomeric excesses; and catalyses the diastereoselective addition of chiral cyanoformates derived from α-methylbenzyl alcohol to aldehydes, a reaction which exhibits double asymmetric induction. © The Royal Society of Chemistry 2006.
