straightforward method for the synthesis of N-substituted imidazole derivatives. 1,1-carbonyldiimidazole mediates the process, which requires no activation group step. We obtained imidazole derivatives in high yields and with short reaction times. To demonstrate the synthetic significance of the aforementioned compounds, we also describe the synthesis of novel ionic liquids from these derivatives.

herein a facile and straightforward method to access 3,4-substituted tetrahydro-1,8-naphthyridines from Morita–Baylis–Hillman. The strategy is based on a tandem sequence involving a Michaeladdition reaction followed by an intramolecular SNAr reaction on a silylated-Morita–Baylis–Hillman adduct. In a single step, a new cycle is formed and the relative stereochemistry of two new centers is controlled
