  First Syntheses of Caerulomycin E and Collismycins A and C. A New Synthesis of Caerulomycin A

  摘要：

  Caerulomycins produced by Streptomyces caeruleus, and collismycins more recently isolated from Streptomyces species, are bipyridinic molecules endowed with antibiotic and cytotoxic activities. The first syntheses of caerulomycin E (1), as well as new syntheses of caerulomycin A (2), are reported. Methodologies involving efficiently controlled reactions such as metalation and cross-coupling reactions have been developed from 2,2'-bipyridine. The functionalization at C-6 could be achieved by metalation of 2,2'-bipyridine N-oxides 5 and 12. 6-Halo-4-methoxy-2,2'-bipyridines (6, 10, 11) became key-molecules of these different pathways, and further functionalization at C-5 allowed the first syntheses of collismycins A (3) and C (4).
