2-Amino-2-deoxyhexoses can be analyzed by gas–liquid partition chromatography of their 2-acet-amido-1,3,4,5,6-penta-O-acetyl-2-deoxyglycitol derivatives prepared by borohydride reduction of the aminoglycoses followed by acetylation of the resulting aminoglycitols with acetic anhydride in the presence of sodium acetate.

Type I

4-(2-Nitrobenzylidene)-2-pyrazolin-5-ones (I) were best prepared by heating o-nitrobenzaldehyde and 2-pyrazolin-5-ones in acetic anhydride containing fused sodium acetate (cf. Erlenmeyer azlactone synthesis). Pyrazolones of type I were reductively cyclized with cyclohexene and palladium–charcoal, and gave 3a,4,9,9a-tetrahydro-9-hydroxy-1H-pyrazolo-[3,4-b]quinolines (II) which, as expected, were amphoteric compounds. Of the three other methods of reduction used in this study, two (zinc and acetic acid; sodium borohydride and palladium–charcoal) were capable of producing pyrazoloquinolines, but were less reliable. The other method employed (hydrazine hydrate and palladium–charcoal) caused degradation of the pyrazolone molecule in the two cases examined, and in both, bis(2-aminobenzylidene) hydrazine (V) was the reduction product isolated.

Cis And Trans

A versatile synthetic route to pterosins, sesquiterpenoid indanones present in bracken, Pteridiumaquilinum, has been developed. The route is exemplified by the synthesis of (2S,3S)-pterosin C by Friedel–Crafts bisacylation of the methyl ether of 2-(2,6-dimethylphenyl)ethanol with methylmalonyl chloride. Demethylation of the resulting 1,3-indandione and reduction with zinc and acetic acid in the presence of acetic anhydride and sodium acetate afforded a mixture of racemic cis and trans isomers of pterosin C diacetate, which was hydrolysed to the corresponding pterosins. Separation and resolution via the S-(+)-α-phenylbutyric esters gave (2S,3S)-pterosin C and (2R,3R)-pterosin C. Other pterosins were prepared as racemates from the 1,3-indandione.

The key precursor rac-2-(4-isobutylphenyl)ethyl-1,2,4-triazole-5-thione (3) was synthesized in good yield from Ibuprofen (1). One-pot three-component reactions of 3 with 5-aryl-furan-2-carboxaldehydes/ substituted aromatic aldehydes and monochloroacetic acid in acetic acid in the presence of acetic anhydride and anhydrous sodium acetate afforded substituted thiazolo[3,2-b][1,2,4]triazole derivatives 4 and 5. The structures of the newly synthesized compounds were elucidated by elemental analyses and spectral data. The compounds were tested for their in-vitro antimicrobial activities.

Acetyl glycine were prepared from glycine acetic anhydride and then 2, 4-disubstituted Oxazol-5-one were prepared from acetyl glycine, substituted aldehydes, acetic anhydride, and sodium acetate as a catalyst. The formed product is evaluated and characterized by thin layer chromatography, infrared spectroscopy and melting point. The, β- unsaturated shows ability to react with various nucleophilic reagents for synthesis of new fused oxazole compounds.

Primary leaves of 17-day-old-bean(Phaseolus vulgarisL. ‘Black Valentine’) were treated with14C-labeled dimethylsulfoxide (DMSO), 3,6-dichloro-o-anisic acid (dicamba), 1,1′-dimethyl-4,4′-dipyridinium salt (paraquat), and 2-chloro-4-(ethylamino)-6-(isopropylamino-s-triazine (atrazine). Each herbicide was tested alone, and in combination with 30% DMSO, 0.25% Tween 80 (nonionic surfactant containing polyoxyethylene sorbitan monooleate), or both. DMSO at concentrations of 25% or more caused varying degrees of acute toxicity. However, a small amount of radioactive carbon generally was distributed throughout the plant 5 days after application of DMSO-14C, as determined by autoradiography and counting. Tween 80 enhanced whereas DMSO had little effect on the absorption and translocation of dicamba, a phloem-mobile herbicide. The contact toxicity and apoplastic movement of paraquat was increased with DMSO. Tween 80 enhanced eight-fold and DMSO, two-fold, the foliar uptake and (apoplastic) movement of atrazine within the treated leaves.
