'On Water’’ Promoted Ullmann-Type C–N Bond-Forming Reactions: Application to Carbazole Alkaloids by Selective N-Arylation of Aminophenols
Autor: Tirtha Mandal, Jyotirmayee Dash, Gargi Chakraborti, Sushovan Paladhi
Publikováno v: The Journal of Organic Chemistry. 83:7347-7359
The Ullmann-type cross coupling of a variety of aromatic, aliphatic amines with aryl halides is reported using a CuI-based catalytic system in combination with an easily accessible prolinamide ligand in aqueous media. The method is mild and tolerant

Autor: Sushovan Paladhi, Hailong Yan, Min-Jung Jung, B. Senthil Kumar, Sang Yeon Park, Yidong Liu, Choong Eui Song
Publikováno v: Organic Letters. 19:3279-3282
The potential of Song's chiral oligoethylene glycols (oligoEGs) as catalysts was explored in the enantioselective protonation of trimethylsilyl enol ethers in combination with alkali metal fluoride (KF and CsF) and in the presence of a proton source.

Selective recognition of c-MYC G-quadruplex DNA using prolinamide derivatives
Autor: Ajay Chauhan, Jyotirmayee Dash, Manish Debnath, Sushovan Paladhi
Publikováno v: Organic & Biomolecular Chemistry. 14:5761-5767
Herein we report the design, synthesis, biophysical and biological evaluation of triazole containing prolinamide derivatives as selective c-MYC G-quadruplex binding ligands. A modular synthetic route has been devised for prolinamide derivatives using

Kinetic Resolution of β-Hydroxy Carbonyl Compounds via Enantioselective Dehydration Using a Cation-Binding Catalyst: Facile Access to Enantiopure Chiral Aldols
Autor: Do Hyun Ryu, Sushovan Paladhi, Insoo Hwang, Choong Eui Song, Eun Jeong Yoo
Publikováno v: Organic letters. 20(7)
A practical and highly enantioselective nonenzymatic kinetic resolution of racemic β-hydroxy carbonyl (aldol) compounds through enantioselective dehydration process was developed using a cation-binding Song's oligoethylene glycol (oligoEG) catalyst

Asymmetric Aldol Reaction of Thiazole-Carbaldehydes: Regio- and Stereoselective Synthesis of Tubuvalin Analogues
Autor: Jyotirmayee Dash, Joydeb Das, Mousumi Samanta, Sushovan Paladhi
Publikováno v: Advanced Synthesis & Catalysis. 356:3370-3376
Tubuvalin derivatives are prepared by a regio- and enantioselective L-proline-catalyzed aldol reaction of thiazole carbaldehydes with acetone and a corresponding prolinamide-catalyzed transformation of 2-formylthiazole-4-carboxylate with methylisopro
