Abstract:
A comprehensive and efficient Tamarind (Tamarindous indica) juice catalysed one pot synthesis of benzopyranopyrimidines in aqueous medium through condensation of 4-Hydroxy-coumarin (10mmol), various substituted benzaldehydes (10mmol)) and urea/thiourea (20mmol) just by grinding at ambient condition is reported in excellent yield of the product. This is a green chemistry approach, which is need of the hour.
Keywords:Benzopyranopyrimidine; Multi-Component Reaction; Grinding Technique (Green Chemistry); Tamarind Juice
