synthetic strategy has been developed for the construction of substituted indolizines from a unique combination of pyridinium salts and 2-bromoallyl sulfones. This approach does not compromise with the diverse substitutions on both the pyridinium salts and 2-bromoallyl sulfones. Wide substrate scope, operational simplicity, milder reaction conditions and good to moderate yields are the merits associated with
已经开发了一种权宜且不含过渡金属的合成策略,用于从吡啶鎓盐和 2-溴烯丙基砜的独特组合构建取代的中氮茚。这种方法不会与吡啶鎓盐和 2-溴代烯丙基砜的多种取代相妥协。广泛的底物范围、操作简单、较温和的反应条件和良好至中等的产率是与当前方法相关的优点。此外,该方法提供了两种产品,它们适用于生成关键中氮茚构建块库。
