摘要

0-and pChlorobenzaldehyde condense with methyl succinate to give methyl hydrogen cis- yo-chlorophenyl-, and methyl hydrogen cis-yp-chlorophenylitaconate together with di-o- chlorobenzylidene-, and di-p-chlorobenzylidenesuccinic acid. The itaconates are cyclized by acetic anhydride and sodium acetate to methyl Cacetoxy-%, and-6-chloro-2-naphthoate which are converted into 5, and 7-chlorc-l-naphthol, respectively. The anhydride of the di- ...
