Chiral polyvinylpyrrolidinone (CSPVP), complexes of CSPVP with a core species, such as a metallic nanocluster catalyst, and enantioselective oxidation reactions utilizing such complexes are disclosed. The CSPVP complexes can be used in asymmetric oxidation of diols, enantioselective oxidation of alkenes, and carbon-carbon bond forming reactions, for example. The CSPVP can also be complexed with biomolecules such as proteins, DNA, and RNA, and used as nanocarriers for siRNA or dsRNA delivery.

2,5-Dimethoxy-2,5-dihydrofuran and vinyl ethers in the synthesis of functionalised 2-alkylfurans

2,5-Dimethoxy-2,5-dihydrofuran reacts, in the presence of a catalytic amount of MgBr2. Et2O with the appropriate vinyl ether, to give functionalised 2-alkylfurans with good yield and mild reaction conditions, this represents a useful synthetic approach to 2-(2-furo)tetrahydro -furanic or -pyranic moieties. The reaction fails on using deactivated or alpha -substituted vinyl ethers. (C) 2001 Elsevier Science Ltd. All rights reserved.
