Chemistry of Heterocycles and Natural Products
Syllabus: 

Heterocyclics and their importance. Nomenclature, structure, reactivity and synthesis of reduced 3-6 membered O, N and S-containing heterocycles. Aromatic heterocycles, heterocycles containing multiple heteroatoms, modern methods of heterocycle synthesis using organometallic reagents, e.g. C-H activation, olefin metathesis, click chemistry etc. Synthesis of selected heterocylic natural products.

Classification, structure, chemistry and biogenesis of some important mono, sesqui-, di- and triterpenoids.  Sterols and bile acids, estrogens, androgens, gestogens and adrenocortical hormones. Hormone production. Cardiac glycosides. Steroidal triterpenes. Biogenesis of steroids and correlation with terpenoids. Structure, characteristic reactions and general methods of degradation of alkaloids. Total synthesis of selected alkaloids. Natural Pigments such as flavones, flavanones, isoflavones, xanthones, quinones, pterins, chlorophyll and haemin. Structure and stereochemistry of carbohydrates, deoxy and aminosugars, hexonic acid and vitamin C, disaccharides, polysaccharides, inositol. gangliosides and other glycosides. Chemistry of vitamins A,B, C and E.
