substrates in the benzoin condensation. They were treated with aromatio 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

Cyanohydrinesters 1–31 have been prepared from α-ketonitriles and aldehydes using DABCO (1,4-diazabicyclo[2.2.2] octane) as nucleophilic acylation catalyst. The modified piperonal 8 was found to inhibit the formation of thromboxane synthetase.
