Stereochemistry in borohydride reduction of 7-imino-cephems: An improved method for conversion of the 7α-amino- 1-oxa(thia)cephems into the 7β-amino isomers

Sodium cyanoborohydride in methanol containing hydrogen chloride (pH ~3) proved to be an excellent reagent system for smooth and highly stereo-selective reduction of the 7-imino-1-oxa(thia)cephems 6 or their equivalent 7-methoxy amines 8 to the correspond
