Efficient Synthesis of 3,5,6,7-Tetrahydro-4H-cyclopenta [4,5] thieno [2,3-d] Pyrimidin-4-ones


  The title compounds 3,5,6,7-tetrahydro-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-ones(6) were syn-thesized by base catalytic reactions of secondary amines with carbodiimides 4,which were obtained from the aza-Wittig reaction of iminophosphoranes(3) with aromatic isocyanates.……
