Abstract

Biosynthetically inspired manipulation of the antibiotic paromomycin led, in six high-yielding steps, to a ring A harboring an R,β-unsaturated 6′- aldehyde and an allylic 3′-methylcarbonate group. Tsuji deoxygenation in the presence of 5 mol % Pd ₂(dba) ₃ and Bu ₃P granted access to a novel series of 3′,4′-dideoxy- 4′,5′-dehydro ring A hybrids. The neomycin-sisomicin hybrid exhibited superior in vitro antibacterial activity to the parent compound neomycin.
