comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولFacile synthesis of AsP3.
The elements phosphorus and arsenic form tetrahedral P4 and As4 molecules, of which the former is a commodity chemical and the latter unstable. Previously, information on molecules of intermediate composition was limited to a spectroscopic study involving hot gas-phase mixtures of phosphorus and arsenic. The AsP3 molecule has yielded to chemical synthesis and was isolated in solid form as a pur...
متن کاملFacile synthesis of (+/-)-paeonilide.
(+/-)-Paeonilide, a novel monoterpenoid metabolite from the roots of Paeonia delavayi showing anti-platelet activating factor activity, is convergently synthesized in five steps with 59% overall yield. The application of benzoyl peroxide-promoted radical addition of unsaturated ester to aldehyde and subsequent topologically favored cyclization greatly simplified the synthesis.
متن کاملA FACILE SYNTHESIS OF (S) – (-) – PROPRANOLOL
A one-pot synthesis of (S)-(-)-propranolol is reported. Zn(NO3)2/(+)-tartaric acid catalyzed enantioselective synthesis of (S)-(-)-propranolol via kinetic resolution of key intermediate ?-naphthyl glycidyl ether with high optical and chemical yield.
متن کاملRegioselectivity in the ring opening of epoxides for the synthesis of aminocyclitols from D-(-)-quinic acid.
Efficient syntheses of four aminocyclitols are reported. Each synthesis is accomplished in eight steps starting from D-(-)-quinic acid. The key step involves a highly regioselective ring opening of epoxides by sodium azide.
