A one-pot synthesis of new 3-benzylphthalide derivatives was developed by using a strategy based on tetrakis(dimethylamino)ethylene (TDAE). The reactions in the presence of TDAE of substituted benzyl chlorides with methyl 2-formylbenzoate or of substituted methyl-2-formylbenzoates with 4-nitrobenzyl chloride furnished the corresponding isobenzofuran-1(3H)-one products in moderate to good yields.

使用 TDAE 策略合成 3-苄基邻苯二甲酸酯衍生物

使用基于四（二甲氨基）乙烯 (TDAE) 的策略开发了新型 3-苄基苯酞衍生物的一锅法合成。在 TDAE 存在下，取代苄基氯与 2-甲酰基苯甲酸甲酯或取代 2-甲酰基苯甲酸甲酯与 4-硝基苄基氯的反应以中等至良好的产率提供相应的异苯并呋喃-1(3H)-酮产物。
