A novel sulfoxide-directed borane reduction was shown to give a variety of 2-substituted 1,4-dihydrobenzoxathiins. For all substrates evaluated, the reaction is completely stereospecific. Application of this methodology to the chiral synthesis of an artificial sweetener was demonstrated.
一种新颖的亚磺酸盐引导的硼氢化还原反应显示能够生成多种2取代的1,4-二氢苯并噻烷。对于所有评估的底物,该反应完全具有立体选择性。此方法在合成人造甜味剂的手性合成中得到了应用。
