Stereocomplexes formed in atactic poly(methyl methacrylate) (a-PMMA) films cast form different solvents were studied by means of Fourier transform infrared spec
Nitrodisulfides were reduced by SmI2/HMPA in anhydrous THF at room temperature to produce active intermediates (samarium thiolates and amides), which were "livi
3,4-Dihydro-(2H)-1,2,4-benzothiadizine-1,1-dioixdes were prepared in good yields via reductive cyclization of o-nitrobenzenesulfonamides with aldehydes promoted
Two new chiral Ru(II)-sulfonamide complex have been used to catalyze the enantioselective transfer hydrogenation of prochiral ketones and the secondary alcohols
A novel electroanalytical method, oscillographic chronopotentiometry with high and low frequency current, is presented in this paper. With this method, the sens
A new azafluorenone (onychine) alkaloid, 6,7-dimethoxy-5-hydroxy onychine N-oxide, was isolated from the stem and branch of Alphonsea monogyma. Its structure wa
