摘要

the synthesis of the 3-unsubstituted phthalides (5) and their conversion into 1-hydroxy-1- arylphthalans (8), very useful precursors of isobenzofurans (10) and subsequent cycloaddition of them to dimethyl acetylenedicarboxylate as a way of regiospecific transformation of benzoic acids into dimethyl 4-hydroxy-1-(2-methoxyphenyl) naphthalene- 2, 3-dicarboxylates (12)(biaryls highly substituted around the axis), is described.
