Tuning the regioselectivity of the Staudinger reaction for the facile synthesis of kanamycin and neomycin class antibiotics with N-1 modification.
[reaction: see text] A novel method for achieving the desired regioselective reduction of the N-1 azido group on a tetraazidoneamine has been developed that leads to the synthesis of both kanamycin… Expand
