Abstract:
Catalytic [6π + 2π]-cycloaddition of N-carbocholesteroxyazepine with functionally substituted terminal alkynes and 1,4-butynediol was performed for the first time under the action of the Co(acac)2(dppe)/Zn/ZnI2 three-component catalytic system. The reaction gave previously undescribed but promising 9-azabicyclo[4.2.1]nona-2,4,7-trienes (in 79–95% yields), covalently bound to a natural metabolite, cholesterol. The structure of the synthesized azabicycles was confirmed by analysis of one- and two-dimensional (1H, 13C, DEPT 13C, COSY, NOESY, HSQC, HMBC) NMR spectra.

Abstract:
Oxidation of the title bromoalcohol provided the strained ketone, 5-bromo-6-oxo-2-azabicyclo[2.1.1]hexane. Additions of nucleophiles to either this or the debrominated ketone have been used to introduce 5(6)-syn-alkyl and aryl groups, 5(6)-alkylidene linkages, and 5(6)-anti-alkyl and acyl substituents. Facial selectivity is for additions to the 6-bromo-5-ketone and 5-alkylidene azabicycles to occur from the face syn to the nitrogen atom. The bromine atom of the title alcohol has also been replaced by a 6-anti-(1-hydroxyethyl) substituent using a directed radical addition process. The stereosel

Abstract:
Several novel nitrogen containing bicyclic systems have been synthesised and their chemistry investigated. The kinetic and thermodynamic invertomer ratios of N-chloro-1,2,3,4-tetrahydro-2-keto-l, 4-iminonaphthalene derivatives were determined. The results suggested that a repulsive interaction existed between the positive end of the carbonyl dipole and the incoming electrophilic chlorine. Despite reaction under favourable solvolytic conditions, it appeared that homolysis of the N-chloroamines was favoured over heterolysis. Under conditions of negligible inversion, N-chloro-1,4-dihydro-1-methyl

Abstract:
A basic introduction to pyrrolizidine and indolizidine alkaloids has been described along with a selection of recent syntheses of the said compounds. Cycloalkene synthesis by intramolecular Wittig reaction has been reviewed and we describe the utility of this strategy in the formation of nitrogen-bridgehead bicycles which can then be used in alkaloid synthesis. Our initial studies on the viability of this strategy in the synthesis of fused pyrrolidone systems employed a Wittig reaction between 5-acetylpyrrolidin-2-one and vinylphosphonium salts.

Abstract:
The synthesis of 15N-enriched samples of derivatives of the 7-azabicyclo[2.2.1]heptyl system was achieved and 15N n.m.r, spectra were recorded both on enriched samples and, in some cases, at natural abundance. Signals corresponding to the two slowly-inverting isomers were seen in the N-methyl-7-azabicyclo[2.2.1]heptyl systems at low temperatures (-20 C). For the N-chloro-analogues, the nitrogen inversion was slower and the two invertomers could be seen at ambient temperature.

Abstract:
The first objective of this Thesis was the study of the preparation of octhydro-1H-cyclopenta[b]pyridines and octahydro-1H-indoles, through the synthesis of (R)-phenylglycinol derived tricyclic lactams. Following the previous reported methodology a carbon substituent would be present at the carbocyclic ring and we planned to find the conditions for controlling its absolute configuration. Unfortunately, the reaction of ketoester 4 and ketoacid 7, provided undesired enamines 8 and 9. On the other hand, the reaction of ketoacid derivatives 16 and 17 with (R)-phenylglycinol led to a mixture of epi
