CH4214 Heterocyclic Chemistry and Natural Products Alakesh Bisai,
Sanjio S. Zade

Preamble
The heterocyclic compounds and natural products are relatively small molecules, produced
mainly by plants and microorganisms. These organic molecules have a long history of uses
(and misuses) by people, e. g. poisons, cosmetics, dietary supplements, antibiotics, anti-
inflammatory agents, antivirals, perfumes, etc. This course will focus on the medical and
nutritional applications of heterocyclic compounds and natural products. The biosynthetic
pathways that lead to these natural organic compounds as well as chemical synthesis will be
discussed in this course.
