摘要
A concise total synthesis of the very promising anti proliferative macrolide (+)-neopeltolide (1) has been performed in 16 steps. The main steps of this approach are a Ru-II-catalyzed alkyne-enal coupling, a Pd-0-catalyzed desulfurative cross-coupling, and a stereoselective In-III-catalyzed propargylation. Four stereogenic centers out of six have been set thanks to substrate-controlled diastereoselective reactions with minimal reliance on protecting groups.
