Facile synthesis of acyl chitosan isothiocyanates and their application to porphyrin-appended chitosan derivative.
Chitosan (1) was reacted with phenylisothiocyanate in 5% AcOH/H2O to give N-phenylthiocarbamoyl chitosan (2) with a degree of substitution (DS) of N-phenylthiocarbamoyl groups of 0.86 in 87.1% yield. The following acylation of compound 2 with hexanoyl chloride in the presence of pyridine afforded 3,6-di-O-2,3-hexanoyl chitosan isothiocyanate (4a) with a DS of the isothiocyanate groups of 0.70 i...
متن کاملFacile and efficient synthesis methods for one pot synthesis of new polycarbonyl compounds
An efficient and environmental-friendly synthetic route to 1,8-dioxodecahydroacridines derivatives have been developed via multi-component one-pot Hantzsch reaction of various aldehydes and ammonium acetate with 2 equivalents dimedone in the presence of Phosphorus pentoxide supported on aluminaas catalyst under solvent-free conditions. The present approach offersseveral advantages such as s...

Adamantyl metal complexes: new routes to adamantyl anions and new transmetallations.
New routes to 1- and 2-adamantyl anion equivalents are described, starting from commercially available 1- and 2-adamantylzinc bromides and employing reducing metals (Mg; Li). Adamantylmagnesium bromides (both 1-AdMgBr and 2-AdMgBr) can reliably be produced via reaction of the corresponding adamantylzinc bromides with excess magnesium metal. Reactions of adamantylzinc bromides with stoichiometic...
متن کاملFacile 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...
