Abstract:
A group of bicyclic ketones and thiones have been synthesized for homenolization studies. Bicyclo[2.2.1]heptane-2,5-dione (6) undergoes unusually rapid tetramethylation giving 3,3,6,6-tetramethylbicyclo[2.2.1]heptane-2,5-dione (1) in good yield. Treatment of 1 with P2S5 in xylene gave 3,3,6,6-tetramethylbicyclo[2.2.1]heptane-2,5-dithione (2) and 3,3,6,6-tetramethyl 15-oxo-bicyclo[2.2.1]heptane-2-thione (3), which was converted into 4 with Raney nickel.

Abstract:
Both the Strecker and Bucherer–Bergs reactions convert the norbornane keto ester methyl bicyclo[2.2.1]hept-6-one-2-endo-carboxylate into the lactam 6-endo-aminobicyclo[2.2.1]heptane-2-endo-carboxylic acid-γ-lactam-6-exo-carboxylic acid. This lactam is unusually stable and cannot be hydrolyzed to the corresponding amino acid. The stereochemistry in the Strecker reaction, in which the amino group is endo, is contrary to that expected from literature precedent. The stereochemistry in the Bucherer–Bergs reaction, in which the amino group is also endo, has been confirmed by X-ray crystallographic a

Cinnamomum camphora has been used to heal some specific diseases in the Chinese Folk for a long time. In order to explore the wide utilization in biomedicine and spicery, the chemical components of helium volatiles from the fresh branches of C. camphora were studied by TD-GC/MS. The analytical result by TD-GC/MS showed that 50 peaks were obtained from the helium volatiles from the fresh branches of C. camphora and 46 chemical compounds representing 99.993% of the total areas were identified.

In this paper we present an efficient procedure for obtaining ether-protected bicyclo[2.2.1]heptane amines in six steps, from an optically active keto-alcohol norbornane compound, for building the heterocyclic bases of pyrimidine and purine constrained nucleosides. Trityl as protecting group makes it possible to isolate 5-endo-compounds in pure form by selective crystallization, and to isolate the intermediates in the next 3 steps of the reaction by crystallization. With TBDMS, all compounds were obtained as oil. The direct selective reduction of the keto-alcohol norbornane compound gave the p

Abstract:
Novel class of the carbocyclic nucleosides based on bicyclo[2.2.1]heptene/heptane was prepared by two approaches. Thymine analogues were synthesized starting from methyl (1R*,4S*)-bicyclo[2.2.1]hepta-2,5-diene-2-carboxylate1by Michael addition of the thymine salt to the double bond as the key step. The yield and ratio of the isomers of this reaction depended on the used base (DBU, K2CO3). Purine nucleoside analogues were synthesized by the linear synthesis, the purine nucleobase was build-up on the amino group.

Epibatidine (exo-2-(6-chloro-3-pyridyl)-7-azabicyclo[2.2.1]heptane) is an alkaloid isolated from the skin of the Ecuadorian poison frog. It has been known since 1992 and has high binding affinity for nicotinic acetylcholine receptors. Many studies have reported epibatidine to possess analgesic properties, but it is also toxic even in low doses, thus, it cannot be used therapeutically. A wide range of epibatidine analogues have been studied in the hope of reducing their toxicity, and hence exploiting their therapeutic potential A general method for the synthesis of anti-7-functionalised 2-benzy
