multicomponent chemistry. This reagent can be employed as a cyanide source in the Strecker reaction and as convertible isocyanide in the preparation of N‐acyl amino acids by Ugi 4CR/detritylation and free imidazo[1,2‐a]pyridin‐3‐amines by a Groebke–Blackburn–Bienaymé 3CR condensation/deprotection protocol. The mechanisms of these three classical MCRs intersect at the common N‐trityl nitrilium ion intermediate
在这里,我们描述了三苯基甲基(三苯甲基)异氰酸酯在多组分化学中的广泛应用。这种试剂可以用作在的Strecker反应氰化物源和作为在制备可兑换胩ñ -酰基氨基通过的Ugi 4CR /三苯甲基和自由咪唑并[1,2酸一]吡啶-3-胺通过Groebke- Blackburn–Bienaymé 3CR冷凝/脱保护方案。这三个经典MCR的机制在常见的N-三苯甲基腈离子中间体处相交,其可预测的反应性可用于化学选择性转化。
