A Formal Synthesis of Lavendamycin Methyl Ester, Nitramarine, and Their Analogues: A Povarov Approach

A convergent formal synthesis of lavendamycin methyl ester and synthesis of its analogues have been delineated through the Povarov approach. This protocol is also applied to the formal synthesis of nitramarine (3) in good yield.

Copper catalyzed synthesis of quinolinopyrano[2,3-b]carbazole derivatives via Povarov reaction

AbstractAn efficient procedure for the synthesis of pyranocarbazole derivatives using copper catalysed Povarov reaction between aromatic amines and O-propargyl carbazole carboxaldehyde has been developed. Ionic liquid is found to be a good solvent medium. Graphical AbstractCarbazoles represent an important family of heterocyclic compounds that are present in many natural products. Among these, pyranocarbazole alkaloids have spared in the natural product synthesis due to their wide isolation from various plants. An efficient procedure for the synthesis of pyranocarbazole derivatives using copper catalysed Povarov reaction has been developed.
