摘要

Abstract 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.
