A series of novel benzoin esters has been obtained in high yield, in a site selective synthesis, by the acid hydrolysis of a series of 4-benzoyloxy-2-azabuta-1,3-dienes.The oxidation of the benzoin esters allows the preparation of symmetrically and unsymmetrically substituted benzils by a route that is superior, in some cases, to those previously reported.
CYANOHYDRINS AS SUBSTRATES IN BENZOIN CONDENSATION. REGIOCONTROLLED MIXED BENZOIN CONDENSATION

O-Benzoylated cyanohydrins of aromatic aldehydes have been used as one of the substrates in the benzoin condensation.They were treated with aromatic aldehydes under phase-transfer conditions to result in benzoin benzoates.By this method aldehydes which fail to undergo condensation using traditional conditions could be converted into benzoins.By the Umpolung of reactivity of the pertinent aldehyde it was possible to prepare both isomeric unsymmetrical benzoins, including the thermodynamically less stable ones.
