✦ Synopsis

Stereoselective Preparation of 4,5-Dihydroxy-5,6-dihydro-4H-1,2oxazines and Their Derivatives.

-cis-Dihydroxylation of the oxazines (I) yields, with exception of (IId), diastereomerically pure 4,5-dihydroxylated 1,2-oxazines which can be converted to a number of derivatives by standard methods.
