An efficient palladium-catalyzed decarboxylative cycloaddition process of vinyl cyclic carbonates and vinyloxazolidinones for the synthesis of highly substituted δ-lactone and δ-lactam derivatives was developed. This protocol exhibits several unique characteristics, including broad substrate scope, good functional group tolerance, and operational convenience, which enables a regioselective access to
开发了一种高效的钯催化的乙烯基碳酸酯和乙烯基恶唑烷酮的脱羧环加成法,用于合成高度取代的δ-内酯和δ-内酰胺衍生物。该方案具有几个独特的特征,包括广泛的底物范围,良好的官能团耐受性和操作便利性,从而可以以中等至良好的产率选择性地进入各种内酯和内酰胺支架。氧化还原中性催化系统通过原位产生环状四取代的双键官能团促进取代的支架的形成。
