SYNTHESIS OF THE ENANTIOMERS OF ERYTHRO-2-OXIRANYL-1,4-BENZODIOXAN
Clark, Robin D.,Kurz, Lilia J.
, p. 2005 - 2012 (2007/10/02)
(2R,1'S) and (2S,1'R)-2-Oxiranyl-1,4-benzodioxan (2R,1'S-1 and 2S,1'R-1) were prepared in six steps from 2-benzyloxyphenol.The key step in each synthesis was the enantioselective Sharpless epoxidation of allylic alcohol 4.
