of phenylglycinol derivatives with terminal and internalalkynes directed by picolinamide auxiliary has been developed. This method offers an efficient and highly regioselective route for the synthesis of 1-hydroxymethyltetrahydroisoquinolines. The reaction employs commercially available Co(II) catalyst in the presence of Mn(III) cooxidant and oxygen as a terminal oxidant, and proceeds with full preservation
An efficient method for the synthesis of 3-hydroxymethyl isoindolinones via cobalt-catalyzed C(sp2)–H carbonylation of phenylglycinol derivatives using picolinamide as a traceless directing group is demonstrated. The reaction proceeds in the presence of a commercially available cobalt(II) tetramethylheptanedionate catalyst and employs DIAD as a “CO” surrogate. This synthetic route offers a broad substrate
