Syntheses of Enantiopure 3,4‐Diamino‐1‐substituted Pyrrolidines.

Abstract

Syntheses of Enantiopure 3,4-Diamino-1-substituted Pyrrolidines. -Key step of the described approach is the twofold substitution of dimesylates (III) with azide. Use of LiN3 instead of NaN3 permits the synthesis of diazides (IV) in satisfactory yields. -(MARSON*, C. M.; MELLING, R. C.; Synthesis 2006, 2, 247-256; Christopher Ingold Lab., Dep. Chem., Univ.
