Module 2 :
3.1. Hydride transfer reagents from Group III and Group IV in reductions – LiAlH4, DIBAL-H, Red-Al, NaBH4 and NaCNBH3 -selectrides, trialkylsilanes and trialkylstannane. Aluminum isopropoxide (oxidation and reduction).Reagents such as NBS – DDQ and DCC.Gilmann reagent – DMAP-Borane, PCC,DEAD (Mitsunobureaction).
Construction of Carbocyclic and HeterocyclicRingSystems
- Synthesis of four, five and six-membered rings – photochemical approaches for the synthesis of four membered rings-oxetanes and cyclobutanes – ketene cycloaddition (inter and intra molecular) – Pauson-Khand reaction -Volhardtreaction – Bergman cyclization – Nazarovcyclization – cation-olefin cyclization and radical-olefin cyclization.
- Inter-conversion of ring systems (contraction and expansion) -Demjenov reaction – Reformatsky reaction. Construction of macrocyclic rings-ring closing metathesis (Grubb’scatalyst).
- Formation of heterocyclic rings: 5-membered ring heterocyclic compounds with one or more than one hetero atom like N, S or O – pyrrole – furan – thiophene – imidazole – thiazole -oxazole.
