摘要

An expeditious synthesis of novel 3,4-dihydropyrimidin-2(1H)-one derivatives has been developed using a multi-component reaction involving the in situ generation of non-commercial beta-ketoesters via transesterification of tert-butyl-beta-ketoester with corresponding alcohol followed by the Biginelli reaction with arylaldehyde and urea in one-pot at 110 degrees C under green conditions.
