Abstract

The title compounds are synthesized starting from 4,10-dichlorochrysene (I) by C—H borylation followed by substitution of firstly 2,8-positions affording derivatives (V) and secondly 4,10-positions (VII).

Abstract

The application of a new benzannulation reaction for the regiocontrolled synthesis of functionalized chrysenes is reported. The initial benzannulation and the subsequent halogen displacement reactions are both highly regiospecific, which thereby enables the regiocontrolled synthesis of a variety of 4,10-disubstituted chrysenes from commercially available 1,5-dihydroxynaphthalene.
