The novel bicyclomycin C(3') tertiary amines 6-8 were prepared in which morpholine, N-acetylpiperazine, and N-carboethoxypiperazine were installed at the C(3') site in bicyclomycin (1), respectively. Previous attempts to synthesize bicyclomycin C(3') amines were unsuccessful. Compounds 68 were found to be more reactive than 1 in neutral and basic solutions. Under these conditions, a novel ring fragmentation
