Employing bio-waste caffeine carbon-supported heterogeneous cobalt catalyst, synthesis of various substituted pyrrole derivatives is reported. In this methodology, pyrroles were synthesized through coupling between nitroarenes and alkenyl diols in a tandem manner. Among all the heterogeneous catalysts Co(OAc)2-CC-800 displayed the highest catalytic activity. Preparative scale synthesis of pyrroles and synthesis of anti-tubercular agent 5-(4-(1H-pyrrol-1-yl)phenyl)-1,3,4-oxadiazole-2-thiol revealed the practical applicability of this protocol. Several kinetic experiments and Hammett studies were conducted to understand the probable mechanism and electronic effects on this transformation.

The invention relates to lactam derivatives and a preparation method and application thereof. Compared with the prior art, the invention provides lactam compounds with a novel structure. The compoundsand compositions thereof have remarkable activity in inhibition of the proliferation of cancer cells (including, but not limited to, the liver cancer cell line HepG2 and the lung cancer cell line A549), and the activity of multiple compounds is in the same order of magnitude as the activity of the commercial drug adriamycin or superior to the activity of adriamycin. The compounds of the inventioncan be prepared from N-substituted pyrrole compounds through a reaction, and the preparation method is convenient, rapid and efficient.
