| Research Abstract |
In this project, design and synthesis of some selected carbo- and heteropolycycles have been carried out in order to develop novel organic fine chemicals for industrial use based on polycycles like adamantane. The results can be summarized as follows :
1) A bridge-imine, 4-azahomoadamant-4-ene obtainable readily from adamantane was converted to the corresponding N-oxide, i.e., a novel bridged nitrone, which was shown to be useful intermediate for synthesis of homoadamantano [4,5] fused heterocycles such as isooxazolidines, isooxazolines, and pyrroles etc.
2) A short-step synthesis of quinazoline alkaloids, Rutecarpine and Tryptanthrin has been developed via intramolecular aza-Wittig methodology. A novel route to polyazamacrocycles has been developed via quinazolinone-annelation of lactams, followed by reductive ring-enlargement.
3) A cyclonucleoside, 2,2'-anhydrothymine derivative was shown to be useful inter-mediate for biologically important 3'-substituted arabinonucleosides.
4) A facile synthesis of beta-chloro-beta-trifluoromethyl DELTA^<alpha,beta>-carbonyl compounds has been developed by using transition metal-induced coupling reaction. Also a novel route to indole skeletons via [4+2] cycloaddition reaction of acetyl pyrrole derivatives has been developed. These compounds are expected as useful synthetic blocks for bioactive compounds.
