Abstract An efficient synthesis of substituted 1,3-dihydroisobenzofurans is developed. In this novel route, o-aroylbenzaldehydes, as key intermediates, can be obtained by lead tetraacetate oxidation of N-aroylhydrazones of salicylaldehydes. The mild and general strategy enables the synthesis of various substituted 1,3-dihydroisobenzofurans in high yields. Moreover, this method can be applied to efficiently
摘要开发了一种高效合成取代的1,3-二氢异苯并呋喃的方法。在这种新颖的途径中,可以通过水杨醛的N-芳酰基hydr的四乙酸铅氧化得到作为关键中间体的o-芳酰基苯甲醛。温和而通用的策略可以高产率地合成各种取代的1,3-二氢异苯并呋喃。而且,该方法可以用于有效地合成依他普仑。
