Total Synthesis of Azasugar 1,4-Dideoxy-1,4-imino-D-galacitol
Sadhu, Partha Sarathi,Santhoshi, Amlipur,Rao, Vaidya Jayathirtha Korean Chemical Society 2012 Bulletin of the Korean Chemical Society Vol.33 No.11
A new highly stereoselective synthesis of pyrrolidine azasugar 1,4-dideoxy-1,4-imino-D-galacitol is being reported herein. The synthesis was achieved in a linear sequence and inexpensive chiral source (+)-diethyl tartarate was used as the starting material. The key step involved during the synthesis was Pd catalysed amino cyclization of alkenylamine, Bose modified Mitsunobu reaction and Sharpless asymmetric dihydroxylation.

Photochemical dehydrogenation of 3,4-dihydro-2-pyridones
Sadhu, Partha Sarathi,Ravinder, Mettu,Kumar, Perepogu Arun,Rao, Vaidya Jayathirtha Korean Society of Photoscience 2009 Photochemical & photobiological sciences Vol.8 No.4
Photochemical dehydrogenation of various substituted 3,4-dihydro-2-pyridones was achieved in a very efficient way by employing 10-15 mol% of photo-induced electron transfer sensitizers like 9-cyanoanthracene, 9-cyanophenanthrene and 1-cyanonaphthalene in presence of molecular oxygen, for the first time.
