Abstract
The asymmetric synthesis of 2S,3S- and 2R,3S-3-methyl-2-phenyl-1,4-benzodioxane from (–)-ephedrine is reported. Comparison of the c.d. curves of these compounds with those of the natural neolignans eusiderin and eusiderin C allows the assignment of 2R,3R configuration to eusiderin and of 2R,3S configuration to eusiderin C and eusiderin D.This publication has 3 references indexed in Scilit:
