Accelerated Amination of Baylis–Hillman Acetates Under Ultrasound Irradiation

R, Sajith AM, K. V. D, C. S, Anwar S. Functionalised dihydroazo pyrimidine derivatives from Morita–Baylis–Hillman acetates: synthesis and studies against acetylcholinesterase as its inhibitors

Dihydroazo pyrimidine derivatives were synthesized at room temperature using MBH acetates and aminoazole derivatives. The in vitro studies carried on a couple of derivatives exhibited much higher potency for Alzheimer's disease (AD).

Synthesis of imidazopyridines from the Morita-Baylis-Hillman acetates of nitroalkenes and convenient access to Alpidem and Zolpidem

A variety of functionalized imidazo[1,2-a]pyridines have been synthesized through a one-pot, room temperature, and reagent-free reaction between MBH acetates of nitroalkenes and 2-aminopyridines. The reaction involves a cascade inter-intramolecular double aza-Michael addition of 2-aminopyridines to MBH acetates. Our methodology is marked by excellent yield, regioselectivity and, above all, adaptability to synthesize imidazopyridine-based drug molecules such as Alpidem and Zolpidem.
