via a versatile pyrrolidine template derived from a stereocontrolled [3+2] azomethine ylide–alkene cycloaddition. Differential ester protection allows for the selective formation of either a bridged bicyclic or tricyclic scaffold via pyridone cyclization. Solid-phase diversification of the pyridone scaffolds yielded a diverse library of 15,000 compounds enabling the discovery of a novel class of Bcl-2
可以通过通用的吡咯烷模板(通过立体控制的[3 + 2]偶氮甲碱内酯-烯烃环加成反应)获得四个对映体纯的基于胱氨酸的支架。差异酯保护允许通过吡啶酮环化选择性地形成桥联的双环或三环支架。吡啶酮支架的固相多样化产生了15,000种化合物的多样化文库,从而能够发现一类新型的Bcl-2抑制剂。
