Modular Design Of Fluorescent Cation Sensors On A Bile Acid Scaffold
(2011-08-05)Bile acid-based cation sensors involving through space photo-induced electron transfer (PET) processes have been synthesized. In this approach, appropriate known fluorophores and aza crown ether receptor units were attached ... -
Molecular Construction Using Carbene and Diboron Systems: Catalytic Transformation of C-C and C-Hetero Atom Bonds
The thesis presents an unconventional approach for the molecular construction using carbenes as the carbon source, and water as the hydrogen source. A gold-catalyst has been used to transfer the carbenes to effect ... -

N-Heterocyclic Carbene (NHC)-Catalyzed Stereoselective Synthesis of Six-Membered Heterocycles and Carbocycles
N-Heterocyclic carbene (NHC) based catalysis is employed for the generation of α,β-unsaturated acylazoliums followed by their interception with various nucleophiles, the formal [3+3] annulation reactions for the construction ... -
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 ... -
N-Heterocyclic Carbene-Catalyzed Enantioselective Synthesis of C-O Axially Chiral Diaryl Ethers, Tricyclic Lactones and Lactams
N-heterocyclic carbene (NHC)-catalyzed transformations with distinctive activation modes allow the facile synthesis of atropoisomers. In this context, we have demonstrated the NHC-catalyzed synthesis of axially chiral diaryl ... -
N-Heterocyclic Carbene-Catalyzed Synthesis of C–N Atropisomers and Heteroatom Chiral Molecules
Asymmetric catalysis has received worldwide interest due to the increasing demand for optically pure compounds in pharmaceuticals, agrochemicals, natural products, and materials science. Traditionally, research in this ... -
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 ... -
NanoPhotoCatalysis: A New Dimension in Synthetic Chemistry
Photocatalysis has emerged as a powerful tool in recent years to drive chemical transformations via electron/energy transfer, allowing access to several unstable or high energy intermediates. Thus, the design and ...
