The synthesis and applications of 4-isocyanopermethylbutane-1,1,3-triol (IPB) as a new convertible isonitrile (isocyanide) for isocyanide-based multicomponent reactions (IMCRs) like Ugi, Ugi-Smiles, and Passerini reactions are described. The primary products obtained from these IMCRs can be converted into highly activated N-acylpyrroles, which upon treatment with nucleophiles can be transformed into
描述了4-异氰基过甲基丁烷-1,1,3-三醇(IPB)作为一种新的可转换的异腈(异氰化物)的合成方法,并用于基于异氰酸酯的多组分反应(IMCR),如Ugi,Ugi-Smiles和Passerini反应。从这些IMCR获得的初级产物可以转化为高度活化的N-酰基吡咯,其在用亲核试剂处理后可以转化为羧酸,酯,酰胺,醇和烯烃。在这个意义上的试剂可以被看作是一个中性碳负离子相当于甲酸盐(HO 2 Ç - ),和羧酸盐或甲酰胺等。(RNU-CO - )。
