Difuntionalised oxirane systems. Stereodivergent synthesis of 1,4;2,3-dianhydro-5-O-benzyl-l-lyxitol and -l-ribitol
摘要:
A simple, efficient, stereoselective synthesis of the diastereoisomeric cis/trans pair of difunctionalized 1,2-epoxides, 1,4;2,3-dianhydro-5-O-benzyl-L-lixitol 1 and 1,4;2,3-dianhydro-5-O-benzyl-L-ribitol 2 is described. Starting from D-(+)-xylose, the synthetic approach to 1 and 2 proceeds through the common intermediate, diol 6, and an appropriate sequence of selective functionalizations.
