摘要: A simple, economical, and environmentally benign protocol has been described for one-pot synthesis of 15-(aryl)-3,3,11,11-tetramethyl-15-azadispiro[5.1.5.3]hexadecane-1,5,9,13-tetrone by pseudo six-component condensation between formaldehyde, dimedone, aromatic amine using the dual role acetic acid as solvent catalyst at room temperature. Ambient conditions avoidance conventional work-up well purification procedure qualify this economical cost-effective “green synthesis”. High efficiency, inexpensiveness, non-toxicity are interesting features methodology, which make it eco-friendly highly attractive. One important advantages methodology compared to previous methods is that electron-withdrawing substituent anilines also give desired product was not possible methodologies Kozlov Mukhopadhyay.
