Abstract:Here we report a conceptual protocol to construct 4-alkynyl furan-2(5H)-one derivatives efficiently through Rh(III)/Cu(I) co-catalyzed highly regioselective oxy-alkynylation of 2,3-allenoic acids with terminal alkynes under mild aerobic conditions with atom...
A method for the tandem cyclization/alkynylation of allenoates with iodoalkynes via gold catalysis under light irradiation is described. Mechanistic studies support that an energy-transfer event takes place, rather than a redox pathway.
