[摘要]:A stereoselective total synthesis of (-)-6-epi-centrolobine, an unnatural analog of (-)-centrolobine, starting from readily available tri-O-acetyl-D-glucal was described. The key steps involved in this synthetic approach are stereoselective C-glycosidation, dehydroxylation and Wittig reaction. The target mol. was achieved in 9 steps with 49% overall yield. |
