Benzyltriethylammonium Tetrathiomolybdate: Applications in Organic Synthesis This thesis deals with the chemistry of benzyltriethylammonium tetrathiomolybdate, [PhCH?NEt?]?MoS?, and its utility as a reagent in organic ... -
Bile Acid Based Molecular Tweezers And Crown Ethers
(Indian Institute of Science, 2005-05-02)Chapter 1. Introduction to Molecular Tweezers Whitlock and Zimmerman developed a class of molecular hosts, popularly known as molecular tweezers, which sandwich aromatic guests by ii=ii interaction. Chapter 1 summarizes ... -
Bile Acid Based Supramolecular Gels, Semiconductor Nanocrystals And Soft Hybrid Materials
(2016-04-12)Chapter 1. General Introduction This chapter gives an introduction to supramolecular organo/hydrogels and the related bile acid chemistry touching upon the gelation properties of the bile acid derivatives. Diverse ... -
Bile Acid based Supramolecular Gels, Soft Hybrid Materials and their Applications
(2017-12-16)Chapter 1. Supramolecular Gels and their Applications Supramolecular gels are viscoelastic materials composed of a solid like three dimensional fibrillary network that is embedded in a liquid. Supramolecular gels are derived ... -
Bile Acid Derived Adaptive Dendrons And Anion Receptors
(2011-02-15)Chapter 1. Bile acid derived adaptive dendrons Bile acids are naturally occurring rigid, chiral molecules with unique facial amphiphilicity making it an attractive build block for designing supramolecular systems. ... -

Bile Salts in Supramolecular Chemistry: Synthesis of Fluorescent Nanoclusters, Oxide Nanoflowers, and Anion Effect on Metallogels
In summary, we have explored an interesting pH-dependent sensitization of Tb(III) using methyl salicylate (MS) as a sensitizer in aqueous media. Methyl salicylate was found to be a specific sensitizer for Tb(III) but not ... -
Binding of 9-N-butyladenine with carboxylic acids : Studies on the watson-crick vs. Hoogsteen selectivity
It’s been shown that if the carboxylic group of the acid is in resonance with the adjacent R group, a net preference for the HG site is observed. If the resonance is disrupted in case of aromatic acids by tilting the plane ... -
biodegration of monoterpenes by pseudomonas incognita
Terpenoids are ubiquitous in nature. Some soil microorganisms, especially species belonging to Pseudomonas, have the ability to utilize terpenes as the sole source of carbon and energy. This process of mineralization helps ... -
Breaking Symmetry – Organocatalytic Enantioselective Synthesis of Natural and Unnatural Ladderanes
Architecturally unique compounds produced by nature have remained a source of inspiration for organic chemists. Ladderane phospholipids (such as [5][3]PC and [3][3]PC), isolated in the year 2002 from anaerobic ammonium oxidizing ... -
C-H Bond Functionalization and Tandem Cyclization with Alkynoates and Maleimides Using Directing Group Strategy
The thesis presents manganese‒ and rhodium‒catalyzed C‒H bond activation and tandem cyclization reactions. These reactions lead to the construction of carbon‒carbon bonds using directing group strategy. The thesis is divided ... -
Carbon, oxygen- and nitrogen (six membered ring) annulations
The thesis entitled "Carbon-, Oxygen- and Nitrogen- (Six Membered Ring) Annulations by Vilsmeier Reaction" consists of six chapters. Chapter 1 describes the results of investigations of the Vilsmeier reaction on known ... -
Carbon-Carbon and Carbon Heteroatom Bond Forming Reactions: From Organocatalysts to Quantum Dots
Butenolides containing stereogenic centers on the ring, are commonly encountered structural motifs, found in many natural products. Consequently, there has been considerable interest in efficient and stereoselective ... -
Catalysis through molecular association
The thesis entitled "Catalysis through Molecular Association" is divided into four chapters. The objective of the work described here was to develop a new method of ortho-carbonation of phenol in water, at room temperature ... -
Catalytic Asymmetric Direct and Vinylogous Aldol, Michael and Alkylation Reactions
Pyrazoles and pyrazolones are a highly explored and privileged class of aza-heterocycles with a wide range of applications, thereby rendering a recurring interest in their synthesis and functionalization. Majority of the ... -
Catalytic Enantioselective Allylic Alkylative Desymmetrization, Carbon-Carbon and Carbon-Heteroatom Bond Forming Reactions
In summary, we have developed a catalytic enantioselective desymmetrization of prochiral 1,3-dinitropropanes, which proceeds via enantiogroup differentiating allylic alkylation reaction. Functionalized allylic carbonates ...
