An Enantioselective Approach to Synthesis of Advanced Chiral Templates for the Construction of Indolic and Indolizidinic Alkaloids
摘要:
A new approach for the syntheses of chiral indolic and indolizidinic templates is presented. They were obtained in three steps starting from a chiral primary amino-vinylsilane. The key step was the N-acyliminium pi-cyclization, leading diastereoselectively to the formation of the six membered ring templates.
