Crystallization-based resolution of 1,4-benzodioxane-2-carboxylic acid enantiomers via diastereomeric 1-phenylethylamides

Unlike the diastereomeric 1-phenylethylammonium salts, the diastereomeric N-1-phenylethylamides of (S)- and (R)-1,4-benzodioxane-2-carboxylic acid show significant differences in fusibility and solubility so as to be efficiently resolved by precipitation of the less soluble diastereomer (>98% de), while chromatographic purification of the unprecipitated fraction affords the more soluble one (>99% de). Overall, 95% of the former and 80% of the latter are recovered. The hydrolysis of the two resolved amides provides the two acid enantiomers and the resolving amine in quantitative yield and with unchanged stereoisomeric purity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of Methyl 1,4-Benzodioxane-2-carboxylate, you can also check out more blogs about3663-79-4

Synthesis, biological screening and molecular docking studies of some ethylated sulfonamides having 1,4-Benzodioxane moiety

The presented study comprises the synthesis of a new series of ethylated sulfonamides in which 1,4- benzodioxane moietyhas been incorporated. The reaction of 1,4-benzodioxane-6-amine (1) with ethane sulfonyl chloride (2) yielded N-(2,3-dihydrobenzo[1,4]dioxin-6-yl)ethanesulfonamide (3), which further on treatment with various alkyl/aralkyl halides, 4a-r, in N,N?-dimethylformamide (DMF) and in the presence of lithium hydride (LiH) acting as a weak base and catalyst;yielded derivativesofN-alkyl/aralkyl substituted N-(2,3-dihydrobenzo[1,4]dioxin-6- yl)ethanesulfonamides (5a-r). The characterization of these derivatives was carried out by different spectroscopic techniques like infra red, proton-NMR and mass spectrometry; then screened against various enzymes i.e. acetylcholinesterase, butyrylcholinesterase, lipoxygenase and alpha-glucosidase enzymes and five different bacterial strains. The synthesized compounds were found to be good inhibitors of lipoxygenase but moderate inhibitors of AChE, BChE and a-glucosidase; whereas compounds 3, 5a, 5f, 5n and 5r were found good antibacterial compounds. The interaction between inhibitors and target enzymes (cholinestrases and lipoxygenase) was computationally observed which correlated with the experimental results.

Anti-HIV-1 screening of (2E)-3-(2-chloro-6-methyl/methoxyquinolin-3-yl)-1- (aryl)prop-2-en-1-ones

Biological studies of two series of 38 quinolinyl chalcones (4a-s and 5a-s) were investigated for their in vitro anti-HIV-1 and cytotoxic activities. Out of 38 compounds, seventeen compounds were observed as good anti-HIV-1 agents with EC50 values less than 20 muM. Compounds 4a, 4l, 4o, 5e, 5h, 5l, 5o, and 5r displayed potent anti-HIV-1 activity with EC50 values less than 5 muM. Among these, compound 5h emerged as the best anti-HIV-1 agent (EC50 = 1.1 muM). Compounds 4d, 4n, 4q, 4r, 4s, 5n, and 5r showed no toxicity in human lymphocytes. Bioassay results show that the type(s) and position(s) of the substituents seem to be critical for their cytotoxic and anti-HIV-1 activities. These results could be useful in the invention of new anti-HIV agents through structural modification.
