Pd-catalyzed coupling reaction of 6-hydroxy-2-(prop-2-yn-1-ylsulfanyl)pyrimidin-4(1H)-one with aryl iodides: efficient syntheses of new 3-benzylthiazolo[3,2-a]pyrimidinones

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

An efficient synthetic protocol was developed for the preparation of 3-benzyl-7(5)-hydroxy-5(7)H-[1,3]thiazolo[3,2-a]pyrimidin-5(7)-ones from 6-hydroxy-2-(prop-2-yn-1-ylsulfanyl)pyrimidin-4(1H)-one and aryl iodides in the presence of Pd–Cu complex catalyst. This one-pot process provides a simple and direct method for the synthesis of new thiazolo[3,2-a]pyrimidinones in good to high yields.
