Regioselective Synthesis of Multisubstituted Furans via Metalloradical Cyclization of Alkynes with α‑Diazocarbonyls: Construction of Functionalized α‑Oligofurans

Co­(III)–carbene radicals generated from activation of α-diazocarbonyls by Co­(II)–porphyrin complexes have been shown to undergo a new type of tandem radical addition reaction with alkynes that affords five-membered furan structures. The Co­(II) complex of 3,5-Di t Bu-IbuPhyrin, [Co­(P1)], is effec...
