摘要
An efficient synthesis of substituted 1,3-dihydroisobenzofurans is developed. In this novel route, oaroylbenzaldehydes, as key intermediates, can be obtained by lead tetraacetate oxidation of Naroylhydrazones 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 synthesize escitalopram.
