Abstract

High selectivity is observed during a Friedel–Crafts acylation/demethylation cascade. In contrast to this cascade, oxygen-containing acylating reagents do not undergo the demethylation step. By the methodology elaborated here, an access is provided to important intermediates for the total synthesis of seminaphthorhodafluor (SNARF) dyes.
