Stereoselective synthesis of Sch 642305, an inhibitor of bacterial DNA primase
摘要:
Sch 642305 is a fungal nonanolide, which inhibits bacterial DNA primase and HIV-1 Tat transactivation. The enantioselective synthesis of Sch 642305 was succeeded starting from useful chiral building block via stereoselective dianion alkylation of beta-ketosulfoxide and lactonization.

stereostructure of glabramycin B, which is an antibacterial 10-membered lactone fused with 4-oxygenated cyclohexanone, was presumed on comparison with related compounds, and concise synthesis of our proposed structure of glabramycin B was achieved via dianion alkylation, Shiina’s lactonization, and Stille cross coupling. We succeeded in the reassignment of its relative configuration.
