Notes:
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 protecting patterns. With glycal 9 as glycosyl donor (and 10) an expedient access to 2′-desamino- (3) and 2′-desamino-2′-epi-hydroxysannamycin A (4) has been opened. For 4 a modest antibacterial activity was found, while 3 was inactive.
