9-Epi-leucomycin A5 Synthesis and antimicrobial activity.

The Journal of Antibiotics, 1981
9-epi-Leucomycin A5 has been obtained from leucomycin A5 (I) by the following reaction sequence. Leucomycin A5 (I) was treated with Collins reagent (CrO3-pyridine) in the presence of water (13%) to provide 9-dehydroleucomycin A5 (II) in 95% yield. The formyl group was internally protected by the reaction of II with acetic anhydride-K2CO3 to afford 18,2'
