HBS Constrained Antiparallel β-Sheets and Flat Toroid Turns; Homoserine, Thioamide and 1,3-Thiazine Containing Peptidomimetics: Design, Synthesis, Conformational Analyses and applications
In chemical biology, short peptidomimetic biological active models have been widely used for anti-microbial activity, drug development, catalysis, and amyloidogenesis. In this thesis, I have synthesized several unnaturally ...
Engineering of Nanomaterials: Application in Antibacterial Activity, Bio-Analyte Detection and Environmental Remediation
Infectious diseases caused by pathogenic bacteria are creating a global health problem. In the recent report of World Health Organization (WHO), it has been mentioned that around 7 lacks people are dying each year worldwide ...
Construction of C-C Bonds by Photocatalysis via Radical Addition Cascade Cyclization (RACC): Synthesis of Heteroatom-Containing Small Molecules
The thesis presents photocatalytic methods for synthesizing small organic molecules at room temperature. The thesis is divided into four sections. Section A presents the general introduction to the thesis. Section B is ...
Employing Arynes in Unique Multicomponent Reactions and a Strain-Release Ene Reaction
Arynes are highly reactive electrophilic intermediates, extensively used for synthesizing various benzo-fused heterocycles and 1,2-disubstituted benzenes. Among the numerous reactions of arynes, multicomponent coupling ...
2,3-Dideoxy Sugars in Glycoconjugations and Cyclic Oligosaccharide Synthesis
2,3- Dideoxy sugars are versatile synthons for organic synthesis. The
applications are diverse in biological systems and organic synthesis. In the first part of the
thesis, 2,3-unsaturated sugars are used for the ...
Functionalized Nanomaterial and Metallocycle for Selective Antibacterial, Diagnosis, and Anti-cancer Activity
The evolution of drug resistant bacteria has become a severe threat to public health globally. The misuse of conventional antibiotics has led to the development of multi-drug resistant bacteria. Even though antibiotics ...
N-Heterocyclic Carbene-Catalyzed Synthesis of Oxazolones, e-Lactones and N-N Axially Chiral Molecules
The diverse reactivity of N-heterocyclic carbenes (NHCs) in organocatalysis is due to the possibility of different modes of action. Although NHC-bound enolates and dienolates were well-known, the NHC-bound cross-conjugated ...
N-Heterocyclic Carbene-Catalyzed Enantioselective Synthesis of Dihydrothiopyranones, Functionalized Benzofurans and Extending Michael Acceptor Aldimine Umpolung
Carbenes exhibit high reactivity as divalent species with six electrons in their valence shell. Their
electrophilic nature arises from an incomplete octet. However, when a heteroatom is introduced adjacent
to the carbene ...
Lanthanide-derived Photoluminescent Hydrogels for Analytical Screening of Norfloxacin, Ofloxacin, α-Chymotrypsin, and Gossypol
Supramolecular gels are soft substances made of elastic cross-linked three-dimensional network connected by noncovalent interactions such as hydrogen bonds, hydrophobic interactions, donor-acceptor interactions, π- π ...
Cp2Ti(III)Cl-Mediated Endo- and Exo-Radical Cyclization: Synthesis of a Tri-nor-guaiane Sesquiterpene Isoclavukerin A, Terpenoid Bicyclic Lactones and Synthetic Studies Towards the Total Synthesis of Scabrolide A
Radical cyclization strategy always gives an expedient access to complex molecular scaffolds present in many bioactive natural products. In this research work, a systematic study is undertaken to investigate the less ...
