An efficient synthesis of Hale and co-workers' C17−C27 bryostatin southern hemisphere intermediate has been accomplished in six steps and 33% overall yield from (R)-2-(benzyloxy)propanal. The synthesis features a one-pot DIBALH/HWE ester homologation as well as a novel acetonide rearrangement/glycal formation cascade.
Hale及其同事的C17-C27抑菌素南半球中间体的有效合成已通过六个步骤完成,从(R)-2-(苄氧基)丙醛的总收率达到33%。该合成具有一锅DIBALH / HWE酯的同源性,以及新型的丙酮化物重排/糖基形成级联反应。
