An efficient method for the synthesis of 3a-hydroxyisoxazolo[3,2-a]isoindol-8(3aH)-ones from CO2, terminal alkynes, EtBr, and NHPI (N-hydroxyphthalimide) was developed through the tandem carboxylation/annulation strategy catalyzed by copper(I)/phosphine system. This one-pot multicomponent...
通过催化串联羧化/环化策略,开发了一种由CO2,末端炔烃,EtBr和NHPI(N-羟基邻苯二甲酰亚胺)合成3a-羟基异恶唑并[3,2-a] isoindol-8(3aH)-的有效方法。通过铜(I)/磷化氢体系。这个一锅多成分...
