Abstract: An efficient and practical method was developed for the synthesis of tetrahydro-1H-pyrrolo[1,2-a]imidazol-2-ones based on the decarboxylative cyclization reaction of α-ketoamides and proline. In most cases, tetrahydro-1H-pyrrolo[1,2-a]imidazol-2-ones were obtained with perfect diastereoselectivity to give trans-isomer in… read more here.

DOI: 10.1021/acsomega.7b00626
Abstract: An efficient tandem intermolecular one-pot aldol condensation/aza-addition reaction of 2-methyl-3-carbamoylpyrroles and aldehydes was developed for the synthesis of 2,3,6,7-tetrahydro-1H-pyrrolo[3,2-c]pyridin-4(5H)-ones. The reaction proceeded using only 3.0 equiv of ammonium acetate promoter in green solvent poly(ethylene glycol)-400… read more here.

DOI: 10.1055/s-0036-1590918
Abstract: An enantio- and regioselective organocatalytic cascade starting from isatin has been disclosed to construct tetrahydrofuranyl spirooxindoles in high yields and stereoselectivities. Also, a triple cascade leading to the pentacyclic compound with two quaternary and a… read more here.
