  • Patent number: 7985856
    Abstract: A method for preparing hexose derivatives comprises the steps of providing a silylated hexose, treating the silylated hexose with a first carbonyl compound in the presence of a catalyst to form an ketalized hexose, treating the ketalized hexose with a second carbonyl compound followed by treating with a first reductant to form an etherized hexose, and converting the etherized hexose into a target hexose derivative, which can be 2-alcohol hexose, 3-alcohol hexose, 4-alcohol hexose, or a 6-alcohol hexose. In particular, the present invention can prepare the hexose derivatives with highly regioselective scheme to protect individual hydroxyls of monosaccharide units and install an orthogonal protecting group pattern in a one-pot manner.

  • Publication number: 20100278659
    Abstract: A pressure-controlling appliance for an inflatable product has a inflatable body, a pump mounted in the inflatable body, a pump switch and an inflation-deflation valve. The pump inflates or deflates the inflatable bodythrough the inflation-deflation valve. The pressure-controlling appliance also comprises an inflation-deflation controlling mechanism and a pressure-controlling mechanism. The inflation-deflation controlling mechanism is applied to open and close the inflation-deflation valve and to turn the pump switch on or off. The pressure-controlling mechanism operates the inflation-deflation controlling mechanism according to the pressure in the inflatable body that compared with the high or low reference pressure.
