Abstract
AbstractA nanocomposite of two‐dimensional MoS2 supported on graphitic C3N4 nanosheets has been prepared by a facile ultrasonication method followed by demonstrating its ability to catalyze the synthesis of several indole derivatives. The as‐prepared nanocomposite catalyst was characterized in detail by using different microscopic and spectroscopic techniques to understand its structure and physicochemical properties. Subsequently, this nanocomposite catalyst was used as a heterogeneous multifunctional catalyst to synthesize several C3‐functionalized indoles in the aqueous medium. The employed strategy also provided very good catalyst recyclability and versatility for the synthesis of various precursors of medicinally significant indoles, such as serotonin, melatonin, and various β‐carboline alkaloids. In addition, a natural product derivate has been prepared on the gram‐scale by using this methodology. Furthermore, high atom economy (100 %) and lower E‐factor (0.042) makes this strategy a sustainable approach for the synthesis of C3‐functionalized indoles.
