The product of a three‐component reaction (3‐CR) is formed only if all reagents, the allenyl isothiocyanate, the nucleophile NuH (sec. amine), and the electrophile E+ (Michael acceptor, aldehyde, etc.) are present at the same time; otherwise a simple thiazole is generated by tautomerism (~ H+).
只有当所有试剂,异硫氰酸烯丙酯,亲核试剂NuH(仲胺)和亲电试剂E +(迈克尔受体,醛等)存在时,才会形成三组分反应(3-CR)的产物。同一时间; 否则,通过互变异构(〜H +)生成简单的噻唑。
