Efficient synthesis of 7-benzyl-5,6,7,8-tetrahydropyrido[4′,3′: 4,5]thieno [2,3-d]pyrimidin-4(3H)-ones via aza-Wittig reaction

7-benzyl-5,6,7,8-tetrahydropyrido[4′,3′:4,5]thieno[2,3-d] pyrimidin-4(3H)-ones were synthesized by base catalytic reactions of nucleophilic reagents (aliphatic amines, alcohols or phenols) with carbodiimides 4, which were obtained from the aza-Wittig reaction of iminophosphoranes 3 with aromatic isocyanates.
