  • Patent number: 9982005
    Abstract: Provided herein are methods of preparing macrolides by the coupling of an eastern and western half, followed by macrocyclization, to provide macrolides, including both known and novel macrolides. Intermediates in the synthesis of macrolides including the eastern and western halves are also provided. Pharmaceutical compositions and methods of treating infectious diseases and inflammatory conditions using the inventive macrolides are also provided. A general diastereoselective aldol methodology used in the synthesis of the western half is further provided.
    Type: Grant

    Date of Patent: May 29, 2018
    Assignee: President and Fellows of Harvard College
    Inventors: Andrew G. Myers, Ian Bass Seiple, Ziyang Zhang
  • Publication number: 20180111956
    Abstract: The present invention provides desosamine and mycaminose analogs and nitro sugars and methods for their preparation. The invention also provides methods of cyclizing a compound of Formula (A?) with glyoxal to give a nitro sugar of Formula (B). Methods for the preparation of compound of Formula (D?) are provided comprising cyclization of a nitro alcohol to give a nitro sugar and reduction and alkylation of the nitro sugar to give a desosamine, mycaminose, or an analog thereof.

  • Publication number: 20150153512
    Abstract: A directional coupler comprising a first and a second optical waveguide extending at least partially parallel to one another is provided. The first and the second optical waveguide are arranged on a substrate in such a way that they extend in common plane running essentially parallel to the substrate. The first and the second optical waveguide are embedded in a polymer cladding. The first optical waveguide comprises a dielectric core and the second optical waveguide comprises a polymer core, or both the first and the second optical waveguide comprise a polymer core, wherein the cross section and/or the composition of the polymer cores is different.
