Preparation of Morpholines and Benzoxazines Starting from Nitroepoxides
摘要:
Nitroepoxides are easily transformed into 2,3-disubstituted morpholines and 2,3-disubstituted benzoxazines in a two-step sequence by treatment with N-methylethanolamine and N-methyl-2-hydroxyaniline, respectively, in a highly stereoselective fashion.
