An efficient Brønsted acid catalyzed conjugate addition of thiocarboxylic acids to in situ-generated ortho-quinone methides (o-QMs) and aza-ortho-quinone methides (aza-o-QMs) has been reported. The reaction has the advantages of broad substrate scope, mild reaction conditions, easy operation and excellent yield. This study provides a new synthetic methodology for the efficient construction of structurally diverse thioesters under mild conditions.

Key words: ortho-Quinone methides, aza-ortho-Quinone methides, Thiocarboxylic acids, Conjugate addition
