Abstract

See full text

Methods are described for efficient and regioselective reactions that are Ru-catalyzed and either (i) amide-directed C—H, C—N, C—O activation/C—C bond forming reactions, (ii) ester-directed C—O and C—N activation/C—C bond forming reactions, or (iii) amide-directed C—O activation/hydrodemethoxylation reactions. All of these reactions of directed C—H, C—N, C—O activation/coupling reactions establish a catalytic base-free DoM-cross coupling process at non-cryogenic temperature. High regioselectivity, yields, operational simplicity, low cost, and convenient scale-up make these reactions suitable for industrial applications. Many previously unknown amide-substituted or ester-substituted aryl and heteroaryl compounds are presented with synthetic details also provided.
