Cu(i)-catalyzed chemical fixation of CO2 with 2-alkynylaniline into 4-hydroxyquinolin-2(1H)-one

A copper(i) catalyzed reaction of 2-alkynylaniline with CO2 using DBU as base to produce 4-hydroxyquinolin-2(1H)-one derivatives in moderate to good yield is presented. In this reaction, a unique bond cleavage pattern for CO2 was observed that one of the C-O double bonds of CO 2 was totally broken and rearranged into two moieties in the absence of the reductive reagent. This efficient reaction system showed the wide generality of substrates including nitro, bromo, cyano and methoxylcarbonyl groups. A possible mechanism containing isocyanate intermediate is proposed.
