Journal ArticleDOI
Synthesis, in vitro antibacterial and antifungal evaluations of new α-hydroxyphosphonate and new α-acetoxyphosphonate derivatives of tetrazolo [1, 5-a] quinoline.
Amol H. Kategaonkar,Rajkumar U. Pokalwar,Swapnil S. Sonar,Vaibhav U. Gawali,Bapurao B. Shingate,Murlidhar S. Shingare +5 more
TL;DR: In vitro antimicrobial activities of the synthesized compounds were investigated against Gram-positive Bacillus subtilis, Gram-negative Escherichia coli and fungi Candida albicans and Aspergillus niger and some of the tested compounds showed significant antimicrobial activity.
Journal ArticleDOI
Synthesis and antibacterial activities of α-hydroxyphosphonates and α-acetyloxyphosphonates derived from 2-chloroquinoline-3-carbaldehyde
TL;DR: In this paper, a modified Abramov reaction using chloro(trimethyl)silane (TMSCl) and subsequent α-hydroxyphosphonate produced were acetylated using acetic anhydride in the presence of 1,8-Diazabicyclo-undec-7- ene (DBU) to afford the α-acetyloxyphosphonic 3a-g in high yields.
Journal ArticleDOI

Swapnil S. Sonar,Sandip A. Sadaphal,Amol H. Kategaonkar,Rajkumar U. Pokalwar,Bapurao B. Shingate,Murlidhar S. Shingare +5 more
TL;DR: The application of solvent-free reaction conditions in organic chemistry has been explored extensively within the last decade as discussed by the authors, and it has been demonstrated to be an efficient technique for various organic reactions.
Journal ArticleDOI
An Efficient Synthesis of 3,4-Dihydro-3-substituted-2H-naphtho(2,1-e)(1,3)oxazine Derivatives Catalyzed by Zirconyl(IV) Chloride and Evaluation of its Biological Activities
Amol H. Kategaonkar,Swapnil S. Sonar,Rajkumar U. Pokalwar,Atul H. Kategaonkar,Bapurao B. Shingate,Murlidhar S. Shingare +5 more
TL;DR: In this paper, a one-pot synthesis of new 3,4-dihydro-3-substituted 2H-naphtho[2,1-e][1,3]oxazine derivatives from 1-Naphthol, various anilines and formalin at room temperature grinding is presented.
Journal ArticleDOI
Simple and High Yielding Synthesis of New α-Aminophosphonates from Imines
Rajkumar U. Pokalwar,Rajkumar V. Hangarge,Balaji R. Madje,Madhav N. Ware,Murlidhar S. Shingare +4 more
TL;DR: In this paper, a simple and high yielding method was developed for the synthesis of novel α-aminophosphonates from imines, obtained from 2-chloroquinoline-3-carbaldehyde, by using triethylphosphite in the presence of chlorotrimethylsilane (TMSCl).
