摘要：

A cooperative catalytic system of heterogeneous polymer-supported bi-metallic platinum/iridium (Pt/Ir) alloyed nanoclusters and 5,5',6,6'-tetrahydroxy-3,3,3',3'-tetramethyl-1,1'-spiro-bisindane (TTSBI) enabled the facile preparation of quinazoline derivatives with low catalyst loadings and broad substrate scope under mild aerobic oxidative conditions. The ability to perform the reaction in gram-scale and under open-air conditions highlights the synthetic application of this cooperative catalytic system.
