Chemical synthesis of β-homonojirimycin, of its N-butyl derivative, and of 'methyl homoazacellobioside'

Saavedra,Martin

, p. 6987 - 6993 (2007/10/03)

β-Homonojirimycin (2) was prepared by the highly stereoselective double reductive amination of a 2,6-heptodiulose derivative (6 or 13) using ammonium formate and NaBH3CN. The process was unsuccessful with primary amines. The synthesis of N-buty
