A metal-free, catalytic CH functionalization of propargyl silyl ethers with imines using the phosphazene base (t-Bu-P4 base) provides structurally defined multisubstituted pyrroles in modest to excellent yields under mild conditions. A one-pot, three-component reaction using silylated acetylenes, aldehydes, and imines is also presented.
使用磷腈碱(t -Bu-P 4碱)对亚丙基的炔丙基甲硅烷基醚进行无金属催化CH官能化,可在温和条件下以中等至极好的收率提供结构明确的多取代吡咯。还介绍了使用甲硅烷基化乙炔,醛和亚胺的一锅三组分反应。
