Enantioselective Synthesis of (+)-Cortistatin A, a Potent and Selective Inhibitor of Endothelial Cell Proliferation
摘要:
This manuscript describes an enantioselective synthesis of the naturally occurring inhibitor of endothelial cell proliferation, cortistatin A. Key steps of the synthesis are a silicate-directed elimination/ring expansion reaction and a highly diastereoselective aza-Prins cyclization with a subsequent transannular etherification.
