The asymmetric introduction of the phenylselanyl moiety using chiral N-phenyselanylacetyloxazolidin-2-thiones and -thiazolidin-2-thiones is reported. The diastereoselectivity is complete in favor of the syn isomer and the aldols so obtained are valuable intermediates for the synthesis of more functionalized molecules such as amino alcohols, after chemoselective activation of the selenium and substitution by nucleophilic nitrogen.
报告中介绍了使用手性 N-苯基硒酰基乙酰基噁唑烷-2-硫酮和噻唑烷-2-硫酮不对称引入苯基硒酰基的方法。在对硒进行化学选择性活化并用亲核氮进行取代后,由此获得的醛醇是合成更多官能化分子(如氨基醇)的重要中间体。
