In order to improve aqueous solubility of nocathiacin I (1), a potent antibacterial agent, N-demethylation of the amino-sugar moiety was sought. Irradiation of 1 in DMF/CH(2)Cl(2) with UV light of 380 nm led to a cyclic product 2, which was hydrolyzed to yield the desired nocathiacin VI (3). Treatment of 1 with shorter UV light caused trans-cis isomerization of a c-c double bond.
