6,7-Dihydro-5H-cyclopenteno[b]pyridine was prepared from 1-amino-2-cyanocyclopentene by acetylation, cyclization and chlorination to give 4-amino-2-chloro-6,7-dihydro-5H-cyclopenteno[b]pyridine, which was subjected to Sandmeyer bromination and then catalytic hydrogenated dehalogenation with an overall yield of about 61%.

Functionalized tetrahydropyridine and piperidine ring systems are widely found in biologically active natural products and pharmaceuticals.

Study on Endo-to Exo-Isomerization of Tetrahydrodicyclopentadiene Catalyzed by Y Zeolites;

Adamantane(ADH) was synthesized by isomerization of endo-tetrahydrodicyclopentadiene(endo-TCD) over supported AlCl_3 catalyst.

Exo-tetrahydrodicyclopentadiene(exo-THDCPD), the isomer of endo-tetrahydrodicyclopentadiene (endo-THDCPD), can be used as an excellent liquid fuel with high density, high heating value and low viscosity at low temperature.

This dissertation is concerned with the approaches to a new high density liquid fuel, tetrahydrotricyclopentadiene (THTCPD), which can be synthesized with dicyclopentadiene (DCPD) as raw materials by three steps: Diels-Alder reaction, separation and hydrogenation.
