A convenient, versatile, and regiospecific synthesis of functionalized 1,3-diarylisobenzofurans has been developed. It involves chemoselective addition of arylmagnesium reagents to the aldehyde function of o-aroylbenzaldehydes, themselves readily obtained by lead tetraacetate oxidation of N-aroylhydrazones of salicylaldehydes. Various functional groups, including nitro, iodo, or ester functionalities
已经开发了方便,通用和区域特异性的官能化的1,3-二芳基异苯并呋喃合成。它涉及芳基镁试剂的化学选择性加成至邻-芳酰基苯甲醛的醛官能团,其本身可通过水杨醛的N-芳酰基hydr的四乙酸铅氧化而容易地获得。因此已将各种官能团,包括硝基,碘或酯官能团,以完全的区域专一性定位在1,3-二苯基异苯并呋喃骨架上。
