A copper-catalyzed intramolecular cyclization reaction of 2-isocyanoacetophenone derivatives to afford 4-hydroxyquinolines chemoselectively is described. The transformation proceeds through enol tautomerism and a subsequent C-C bond formation. Compared to previous methods, this study provides a new protocol for the construction of 4-hydroxyquinoline compounds from functionalized isocyanides under mild conditions.

The development of efficient and environmentally benign palladacycle-phosphine catalyzed process to enable the formation of chemoselective C-alkylated or N-alkylated aminoacetophenones with alcohols is described. This methodology proved to be tunable by variation of the base and the temperature, which allows for the isolation of structurally diverse C-alkylated and N-alkylated aminoacetophenones. Moreover, this methodology has been applied to the synthesis of biologically and industrially important donepezil.
