SOLVENTLESS CYCLOCONDENSATIONS BETWEEN 1-NAPHTHOL AND BENZILS

Department of Chemistry and Central Laboratory, Nankai University, Tianjin 300071

Received Date: 6 July 1993

In the absence of organic solvents, the Lewis acid catalyzed cyclocondensation reactions between 1-naphthol and benzils gave 3-aryl-3-aryl' naphtho[1, 2-b]furan-2(3H)-ones (NFs) in good yields (62%~70%) An electrophilic substitution mechanism involving formation of n-EPD/v-EPA complexes and rearrangement of aryl group was proposed.
