Abstract

Abstract: The transcyanation of aromatic and aliphatic aldehydes 1 (RCHO) with acetone cyanohydrin is catalyzed by the enzyme D-oxynitrilase to afford (R)-cyanohydrins 2 (RCH (0H) CN). The biocatalytic method using acetone cyanohydrin gives products of high enantiomeric purity with better consistency than similar conditions using hydrogen cyanide as the cyanide source. The use of an ether-buffer biphasic solvent system is essential for ...
