Efficient Polymer-Supported Sharpless Alkene Epoxidation Catalyst*
Homogeneous linear poly(tartrate ester) ligands provide high chemical yields and enantiomeric excesses in the epoxidation of trans-hex-2-en-1-ol using Ti(OPr)4-tert-butyl hydroperoxide. Branched poly(tartrate ester) can be use as heterogeneous ligands in the epoxidation of trans-hex-2-en-1-ol using Ti(OPr)4-tert-butyl hydroperoxide. Removal and recovery of the polymer catalyst is a simple filtr...
متن کاملPolymer-supported basic ionic liquid as an efficient heterogeneous catalyst system for straightforward synthesis of flavanones
Aromatic aldehydes are efficiently condensed with 2'-hydroxyacetophenone by polymer-supported basic ionic liquid as an excellent heterogeneous catalyst utilizing the Claisen–Schmidt reaction. Microwave irradiation has been employed, providing flavanone in good yield and short reaction time.

متن کامل4-Dimethylaminopyridine as a catalyst in heroin synthesis.
In this paper, we describe an acetylating method for fast synthesis of heroin from morphine in the presence of 4-dimethylaminopyridine (4-DMAP) as a catalyst. In the reaction which led to heroin formation, the morphine base was subjected to a solution made up of 4-DMAP (catalyst), methylene chloride (solvent) and acetic anhydride (acetylating agent). We showed that in comparison with classic ac...
متن کاملPolymer-assisted solution-phase synthesis of glycosyl chlorides and bromides using a supported dialkylformamide as catalyst.
Glycosyl halides are a very valuable and versatile group of synthetic intermediates widely used in carbohydrate chemistry for the ready functionalization at the anomeric carbon. Thus, glycosyl halides can be easily converted into O-glycosides, C-glycosides, or glycals via the generation of intermediate anomeric carbocations, radicals, or cabanions. Because of their moderate stability, glycosyl ...
