Abstract:
A series of some new 1,3,5-trisubstituted pyrazoles was synthesized by the reaction of α-β dibromochalcones with phenylhydrazine hydrochloride. α-β-Dibromochalcones were prepared by the regioselective bromination of respective chalcones with tetrabutylammonium tribromide. The synthesized trisubstituted pyrazoles were evaluated for their anti-inflammatory and antioxidant properties. Keywords: α-β-Dibromochalcones, 1,3,5-Trisubstituted pyrazoles, Tetrabutylammonium tribromide, Anti-inflammatory and antioxidant activities

Abstract:
Urea groups appear in many biomolecules and polymers. They have a significant impact on the properties of the materials because of their inherent strength and for their ability to participate in hydrogen bonds. Typically, in classical urea-based polymer materials, the urea groups occur in their N,N′-disubstituted state. Recently, bis-aspartates have been introduced as a novel type of hindered amine resins providing, upon crosslinking with (poly)isocyanates, the polyurea–polyaspartate thermosets (PU-ASPE) for coatings, sealants, polyelectrolytes, and other applications. These materials contain

Three new bis 1,3,5-trisubstituted hydantoins were synthesized by combining an Ugi four-component condensation reaction with a base induced cyclization. In the two-step sequence, first three new bis Ugi compounds were synthesized by the Ugi four-component condensation reaction, and then bis 1,3,5-trisubstituted hydantoins were obtained by intramolecular cyclization reaction.

Abstract:
This thesis details a methodology utilising various synthetic pathways towards cyclisation precursors suitable for use in Prins and carbonyl-ene cyclisations to effect 2,3,4-trisubstituted piperidines. Once the precursors were synthesised, we were interested in the stereochemical outcomes of the cyclisations, in particular identity and rational of the kinetic and thermodynamic products and their variation due to differing substituents on C2. Previous work in the Snaith group has addressed various other substitution patterns and 2,3,4-trisubstituted piperidines are central components of a vast

Abstract:
This thesis describes the diastereoselective synthesis of 2,4,5-trisubstituted piperidines using carbonyl-ene and Prins cyclisations and their application in natural product synthesis. Following on from previous work in the group, we investigated how a preinstalled substituent in the 2-position can help to control the sense of induction at the two newly forming stereocentres. We utilised the Prins reaction in the formal synthesis of pseudodistomin F, a marine alkaloid that posses a 2,4,5-tribsubstituted piperidine core.

Several new Mo-bisaryloxide complexes were prepared, and they showed superior efficiency in synthesizing the Z-trisubstituted enoates (vs. corresponding mono-aryloxide pyrrolide complexes). Synthetic utility of the method was demonstrated through several concise syntheses of bioactive triterpenoids and value-added derivatives of prenyl-containing compounds such as citronellal, citronellol, and geraniol, all of
