This report examines the work of in the field of stereochemistry. While not a historical figure like Pasteur or van ’t Hoff, Prof. Sengupta is recognized within academic circles—particularly in the Indian subcontinent—for his contributions to synthetic stereochemistry , chiral auxiliary design , and the pedagogy of stereochemical concepts . His work bridges classical stereochemical rules (e.g., Cahn-Ingold-Prelog, Curtin-Hammett principle) with modern asymmetric synthesis applications.
