Synthesis and antibacterial screening of some 2-(p-substituted benzylidene)-3- (5-ethyl-1,3,4-thiadiazol-2-yl)thiazolidin-4-ones
A series of 2-(p-substituted benzylidene)-3-(5-ethyl-1, 3, 4-thiadiazol-2-yl) thiazolidin-4-ones were synthesized by the reaction of Schiff’s bases of N-(p-substituted benzylidene)-5-ethyl-1, 3, 4-thiadiazole-2-amines with thioglycolic acid in 1, 4-dioxane as solvent and studied for their in vitro antibacterial activity. Reaction of thiosemicarbazide with propanoic acid in presence of concentra...
متن کاملSynthesis of 3- Benzylidene, 5-Substituted 3-Benzylidene, 3- Hetarylmethylene and 5-Substituted Hetarylmethylene Derivatives of In- dolin-2-ones
A wide variety of titled compounds, several of which have neuro-protecting properties has been prepared in yields ranging between 70 to 90%. The compounds were identified by 1 HNMR, 13 C NMR, 1D and 2D NOE analysis, and HRMS. An investigation of the effect of certain 5-substitutuents on the E to Z ratios in DMSO-d6 was carried out. The 5nitro and 5-acetyl substituents were not isomerized, where...
متن کامل5-benzylidenerhodanine and 5-benzylidene-2-4-thiazolidinedione based antibacterials.
Herein we outline the antibacterial activity of amino acid containing thiazolidinediones and rhodanines against Gram-positive bacteria Staphylococcus aureus ATCC 31890, Staphylococcus epidermidis and Bacillus subtilis ATCC 6633. The rhodanine derivatives were generally more active than the analogous thiazolidinediones. Compounds of series 5 showed some selectivity for Bacillus subtilis ATCC 663...
متن کاملPhosphites as ligands in ruthenium-benzylidene catalysts for olefin metathesis.
The use of phosphites in second generation, ruthenium-based olefin metathesis pre-catalysts leads to an improvement in catalyst stability and activity at low catalyst loadings.
متن کاملSolvent-controlled regioselective protection of allyl-4,6-benzylidene glucopyranosides
We wish to report a simple synthetic procedure, which permits the regiospecific mono-acylation, alkylation and silylation at the 2-position of allyl 4,6-O-benzylidene alpha-D-glucopyranoside in high yields and which does not require the use of catalysts.
