  摘要：

  Twenty‐one novel 2‐aryloxy‐3‐(4‐chlorophenyl)‐8‐substituted‐5‐aryl‐8,9‐dihydro‐3H‐chromeno[2,3‐d]pyrimidine‐4,6(5H,7H)‐diones 5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h, 5i, 5j, 5k, 5l, 5m, 5n, 5o, 5p, 5q, 5r, 5s, 5t, 5u were designed and easily synthesized via a tandem aza‐Wittig reaction. Treatment of iminophosphorane 3 with 4‐chlorophenyl iso‐cyanate gave carbodiimide 4, which reacted with phenols to provide the title compounds in 50–73% isolated yields. All compounds 3 and 5 were confirmed by infrared, 1H‐NMR, mass spectra, and elemental analysis, and compound 5a was further analyzed by single‐crystal X‐ray diffraction, and the title compounds were synthesized with the purpose of bringing in some new chemical and biological interests.

  system was developed as a catalyst for the Knoevenagel condensation and Knoevenagel initiated three-component one-pot synthesis of 4H-pyrans at room temperature with high yields and in short reaction times. Further, the EDDF-PEG600 catalytic system was recycled six times without any appreciable loss in its activity and hence can be termed as a green, environmentally benign catalytic system. A plausible
