Chemoselective synthesis of carbamates using CO2 as carbon source
Riemer, Daniel,Hirapara, Pradipbhai,Das, Shoubhik
, p. 1916 - 1920 (2018/08/17)
Synthesis of carbamates directly from amines using CO2 as the carbon source is a straightforward and sustainable approach. Herein, we describe a highly effective and chemoselective methodology for the synthesis of carbamates at room temperature and atmosp
Synthesis and antibacterial activity of isothiazolyl oxazolidinones and analogous 3(2H)-isothiazolones

The synthesis and antibacterial activity of several new 5-((3-oxoisothiazol-2(3H)-yl)methyl)-3-phenyloxazolidin-2-ones 8 and analogous 2-(4-substituted phenyl)-3(2H)-isothiazolones 3 and 4 substituted at 4 and/or 3-positions of the phenyl moiety with different groups of which some have shown to increase the antibacterial activity of both 3-aryl-2-oxazolidinones and 3(2H)-isothiazolones is described. The most active compounds were isothiazolyl oxazolidinones 8a,j with unsubstituted and 8b with 4-F substituted phenyl rings which showed activities higher than analogous 3(2H)-isothiazolones and comparable or superior to linezolid, vancomycin, and ciprofloxacin against some tested microorganisms. The change in position of F and/or the use of larger substituents gave compounds with reduced or no activity. Evaluation of cytotoxicity to mouse fibroblast (NIH/3T3) cells indicated that these compounds exhibit antibacterial activity at non-cytotoxic concentrations.
Synthesis of some heterocycle containing urea derivatives and their anti-viral activity
Verma, Majusha,Singh, Krishna N.,Clercq, Erik D.
, p. 11 - 22 (2007/10/03)
Some new isoindol heterocyclic ureas (6a-6i) have been synthesized using N-aminophthalimide (2) and ethyl N-monosubstituted/ethyl N,N-disubstituted carbamate (5a-5i). All the newly synthesized final compounds have been evaluated for their anti-viral activities against a variety of viruses. The compound (6f) with the methoxy substituent showed reasonably better activity as compared to the standard drugs against all the viruses (cf. Tables 1, 2 and 3). Further, all the products (6a-6i) were found to be active against Vesicular stomatitis virus, Coxsackie virus B4 and Respiratory syncytical virus (cf. Table 2) and the compounds (6h) and (6i) displayed better antiviral activity in comparison to Brivudin and (S)-DHPA (cf. Table 3).
