Cyanohydrins, prepared in high optical purity from aryl aldehydes, have been converted into α- hydroxy aldehydes, β- hydroxy ketones and β- hydroxy amines without any racemization and frequently with good stereoselectivity for the erythro-diastereoisomer (>90%) at the newly introduced stereogenic centre.
