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
芳族醛的邻苯甲酰氰醇已被用作安息香缩合反应的底物之一。它们在相转移条件下用芳香醛处理,得到苯偶姻苯甲酸酯。通过这种方法,在传统条件下无法缩合的醛可以转化为苯偶姻。通过相关醛的反应性的Umpolung,可以制备两种异构的不对称安息香,包括热力学上较不稳定的安息香。
