A stereoselective approach to the angucyclinone antibiotics: A total synthesis of (±)-urdamycinone B
A stereoselective chiral Lewis acid promoted reaction of siloxydiene (±)-13 and dienophile complex 18, gave a 4:1 mixture of urdamycinone B (1) and its C-3 epimer (24) in several steps in 12% overall yield. Separation of these products was achieved by high performance liquid chromatography (HPLC). K...
