Application of Water for Synthesis of Cyclopentadienes via Multi-component Reactions of N-methyl imidazole
A water-accelerated multi-component synthesis of organic target molecules was used as a key method for the preparation of cyclopentadiene derivatives. The three-component condensation reactions of primary amines with alkyl propiolates in the presence of N-methylimidazole in water at room temperature were developed as efficient and clean green synthetic procedures for the high-yielding preparati...
