- Nitromethane as a nitrogen donor in Schmidt-type formation of amides and nitriles
-
The Schmidt reaction has been an efficient and widely used synthetic approach to amides and nitriles since its discovery in 1923. However, its application often entails the use of volatile, potentially explosive, and highly toxic azide reagents. Here, we report a sequence whereby triflic anhydride and formic and acetic acids activate the bulk chemical nitromethane to serve as a nitrogen donor in place of azides in Schmidt-like reactions. This protocol further expands the substrate scope to alkynes and simple alkyl benzenes for the preparation of amides and nitriles.

- Synthesis, Characterization, and Antimicrobial Screening of 4″-methyl-2,2″-diaryl-4,2′:4′,5″-terthiazole Derivatives
-
A series of novel 4″-methyl-2,2″-diaryl-4,2′:4′,5″-terthiazole (8a-p) derivatives has been synthesized and screened for antibacterial activity against four pathogenic bacteria, Escherichia coli, Pseudomonas flurescence, Staphylococcus aureus, and Bacillus subtilis. Among them, compounds 8a and 8j exhibited excellent antibacterial activity with minimum inhibitory concentration range of 1.0 to 5.3?μg/mL and compounds 8m and 8p exhibited moderate to good antibacterial activity with minimum inhibitory concentration range of 16.9 to 29.7?μg/mL against all tested strains. All the synthesized compounds were screened for their in vitro antifungal activity against Cocinida candida. Most of the compounds reported moderate antifungal activity. This study provides valuable directions to our ongoing endeavor of rationally designing more potent antimicrobial agent.

- Hantzsch reaction intermediates as a means to obtain bisthiazoles and 5-acetyl-bisthiazoles
-
The synthesis, chemical and spectral data of some intermediates of Hantzsch's reaction is described. The synthesis of some 4-R-5-R1-2'-Aryl-2,4'-bisthiazoles was presented too. By interaction of acetic anhydride, hydroxythiasoline derivatives were converted to 5-acetyl-bisthiazoles.
