Preparation of pentafluorosulfanyl (SF5) pyrrole Carboxylic Acid esters.
The Journal of organic chemistry, 2009Co-Authors: William R. Dolbier, Zhaoyun ZhengAbstract:Pyrrole derivatives bearing a pentafluorosulfanyl group are currently unknown. In this paper, a facile preparation of SF5-substituted pyrrole Carboxylic Acid esters in good yield is reported. Utilizing the cycloaddition of an azomethine ylide to pentafluorosulfanylalkynes, a series of dihydropyrroles were prepared and oxidized to the respective 1-tert-butyl-4-(pentafluorosulfanyl)pyrrole-2-Carboxylic Acid esters in good yield. Further treatment of these pyrroles with catalytic triflic Acid allowed removal of the tert-butyl group.

nickel catalyzed decarbonylative amination of Carboxylic Acid esters
Journal of the American Chemical Society, 2020Co-Authors: Christian A Malapit, Margarida Borrell, Michael W Milbauer, Conor E Brigham, Melanie S SanfordAbstract:The reaction of Carboxylic Acid derivatives with amines to form amide bonds has been the most widely used transformation in organic synthesis over the past century. Its utility is driven by the bro...

Exploring supramolecular aggregation behaviour of bioactive thiazolidine-4-Carboxylic Acid derivatives
Microsystem Technologies-micro-and Nanosystems-information Storage and Processing Systems, 2018Co-Authors: R. M. Jagtap, S. K. Pardeshi, Aiman Nabi, Zakir Hussain, Masood Ahmad RizviAbstract:A target synthesis of selected biocompatible chiral Thiazolidine-4-Carboxylic Acid derivatives was attempted to investigate the influence of number, type and position of hydrogen bonding functionalities and solvent molecules in the crystal lattice on the supramolecular aggregation behaviour leading to formation of molecular assemblies. The single crystal X-ray diffraction studies of (R)-thiazolidine-4-Carboxylic Acid (T4CA, zwitter ion form), 2-propionyl T4CA and (2S,4R)-3-(tert-butoxycarbonyl)-2-(4-methoxyphenyl)T4CA and other reported thiozolidine 4-Carboxylic Acid derivatives were used to establish the solid state aggregation behaviour. The 1D, 2D and 3D agregrational behaviour of synthesized thiozolidine-4-Carboxylic Acid derivatives was explored from their crystal packing diagrams and was further extended in light of some appropriate literature reported thiozolidine-4-Carboxylic Acid derivatives. The explored 1D, 2D and 3D supramolecular aggregrational behaviour in case of the thiazolidine-4-Carboxylic Acid derivatives can be explored for their further applications as biocompatible supramolecular assemblies towards gas storage, biosensing and template catalysis.
