Synthesis of new heteroaryldi(diindolyl)methanes: Colorimetric detection of DNA by di(diindolylmethyl)carbazoles
Ramu Meesala Rajagopal Nagarajan
We have synthesized di(diindolylmethyl)carbazoles and di(diindolylmethyl)pyrroles by the reaction of substituted indoles with the corresponding carbazole and pyrroledicarboxaldehydes by employing a new catalyst PPh3.CF3SO3H. We have also demonstrated the utility of di(diindolylmethyl) carbazole derivatives for the colourimetric and fluorometric detection of DNA.

Copper catalyzed synthesis of quinolinopyrano[2,3-𝑏]carbazole derivatives via Povarov reaction
Subburethinam Ramesh Rajagopal Nagarajan
An 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.

Copper catalysed synthesis of indolylquinazolinone alkaloid bouchardatine
Mayavan Viji Rajagopal Nagarajan
We describe the total synthesis of indolylquinazolinone alkaloid bouchardatine and some of the quinazolinone derivatives. The aerobic oxidation induced by copper(I) bromide, followed by Vilsmeier-Haack formylation gives the natural product bouchardatine alkaloid in good yield.

Total synthesis of sannanine and analogues thereof
BADHER NAVEEN RAJAGOPAL NAGARAJAN
The first total synthesis of Sannanine has been accomplished with an overall 30% yield in a concise manner. The key strategies involve Friedländer quinoline synthesis, demethylation,
