The facile synthesis of 6- to 8-membered pyrrololactams has been developed using a ringexpansion of spiro-2H-pyrroles, the products of intermolecular alkyne–isocyanide click reactions. The key to successful ringexpansion of spiro-2H-pyrroles to pyrrololactams is the enforced orbital overlap between the internal alkene and the amide carbonyl group through the conformationally locked bicyclic structures

A series of 12 polysubstituted pyrrolo[3,4-b]pyridin-5-ones were synthesized via a one-pot cascade process (Ugi–3CR/aza Diels-Alder/N-acylation/decarboxylation/dehydration) and studied in vitro using human epithelial cervical carcinoma SiHa, HeLa, and CaSki cell line cultures. Three compounds of the series exhibited significative cytotoxicity against the three cell lines, with HeLa being the most sensitive

Catalytic Ugi-Type Condensation of α-Isocyanoacetamide and Chiral Cyclic Imine: Access to Asymmetric Construction of Several Heterocycles
Several novel heterocycles have been constructed asymmetrically on the basis of a catalyticUgi-type condensation of α-isocyanoacetamide and chiral cyclic imine. The combination of phenylphosphilic acid and trifluoroethanol is exploited to promote an Ugi-typereaction with α-isocyanoacetamide for the first time. By means of this reaction, chiral 3-oxazolyl morpholin-2-one/piperazin-2-one derivatives
