Gold and bifunctional thiourea catalyzed asymmetric cycloisomerization/annulation reactions of enynamides and allyl ketones: synthesis of 4,5,6,7-tetrahydrofuro[2,3- b ]pyridines
Dipankar Barman, Rupkumar Khuntia, Subhas Chandra PanWe have developed a highly enantioselective sequential relay catalytic transformation using gold and bifunctional thiourea that produces functionalized enantioenriched polycyclic furan fused N-heterocycles.
