The bifunctional organocatalyst promoted, relaycascade catalysis (use of a single catalyst capable of promoting each catalytic cycle in the designed cascade process) has been the hot area of research in recent times, as it enables the green synthesis of complex molecular architectures in an atom, cost, and step-economic fashion. In this context we summarized the recent developments in the area of the thiourea-tert-amine based cascade catalysis in the current review article. The discussion was divided into three subsections. double-, triple-, and quadruple cascades depending on the number of individual [a] Dr.
