During the total synthesis of calothrixin B, various novel and unexpected results were noticed such as cleavage of C-N bond in imine using sodium cyanoborohydride, sodium methoxide as a hydride source for reduction, deformylation in the presence of bromine, and deacylation using ceric ammonium nitrate (CAN). A detailed mechanism has been proposed for the unexpected results and a few of them are generalized. Temperature dependent NMR studies have been carried out for confirmation of the structure of one of the intermediates in the synthetic sequence.

Three new routes were established for the synthesis of biologically active murrayaquinone A and a new method was developed for synthesis of murrayanine from the same starting material as 4-hydroxy carbazole. During the synthetic course a few novel observation were recorded, which include two one pot reaction sequences and C-N bond cleavage by sodium cyanoborohydride.
