Abstract
Shorter and more efficient routes to 6'-des(N-methyl)sannamycin A (1) and its 2'-epi analog 2 have been elaborated with the proven sannamine -type acceptor 10 and the glycosyl donors 5-8 featuring novel protecti ng patterns. With glycal 9 as glycosyl donor (and 10) an expedient acc ess to 2'-desamino- (3) and 2'-desamino-2'-epi-hydroxysanna-mycin A (4 ) has been opened. For 4 a modest antibacterial activity was found, wh ile 3 was inactive.
