The C24–C40 fragment of (−)-pulvomycin was prepared in enantiomerically pure form using a concise synthesis method (15 linear steps from d-fucose, 6.8% overall yield) featuring a diastereoselective addition to an aldehyde, a β-selective glycosylation and a Stille cross-coupling as the key steps.
使用简洁的合成方法(从d-岩藻糖开始的15个线性步骤,总收率为6.8%),通过对醛的对映选择性加成、β-选择性糖基化和Stille交叉偶联等关键步骤,制备了(-)-pulvomycin的C24-C40片段,且其对映体纯度高。
