  • Publication number: 20150165408
    Abstract: A fluid-sparged helical channel reactor can include a constrained flow unit located within a reactor body. The unit has an inner wall and an outer wall which produces a helical constrained flow along a substantially enclosed helical flow path around an axial interior volume. At least part of the outer wall includes a sparging portion to allow fluid reactant to be sparged into the helical constrained flow. A liquid inlet fluidly connected to the reactor body and configured to allow addition of a liquid into the enclosed helical flow path. A sparging fluid inlet is fluidly connected to the reactor body which supplies a sparging fluid to the sparging portion of the constrained-flow unit. A liquid outlet fluidly is connected to the reactor body to allow removal of liquid from the constrained-flow unit. A gas outlet is fluidly associated with the enclosed helical flow path to allow removal of gases from the enclosed helical flow path.

  • Patent number: 8114970
    Abstract: Preparation of synthetic monosaccharides, for use in the preparation of synthetic heparinoids.
    Type: Grant
    Filed: January 15, 2009
    Date of Patent: February 14, 2012
    Assignee: Alchemia Limited

  • Publication number: 20110201794
    Abstract: Methods are described for the preparation of combinatorial libraries of potentially biologically active disaccharide compounds. These compounds are variously functionalized, with a view to varying lipid solubility size, function an other properties, with the particular aim of discovering novel drug or drug-like compounds, or compounds with useful properties. The invention provides intermediates, processes and synthetic strategies for the solution or solid phase synthesis of disaccharides, variously functionalized about the sugar ring, including the addition of aromaticity and charge, and the placement of pharmaceutically useful groups and isosteres.
