  • Publication number: 20200223864
    Abstract: The invention provides methods for the synthesis of eribulin or a pharmaceutically acceptable salt thereof (e.g., eribulin mesylate) through a macrocyclization strategy. The macrocyclization strategy of the present invention involves subjecting a non-macrocyclic intermediate to a carbon-carbon bond-forming reaction (e.g., an olefination reaction (e.g., Horner-Wadsworth-Emmons olefination), Dieckmann reaction, catalytic Ring-Closing Olefin Metathesis, or Nozaki-Hiyama-Kishi reaction) to afford a macrocyclic intermediate. The invention also provides compounds useful as intermediates in the synthesis of eribulin or a pharmaceutically acceptable salt thereof and methods for preparing the same.

  • Patent number: 10224086
    Abstract: A memory device includes at least one reference cell and multiple memory cells. A method of operating the memory device may include detecting a temperature of the memory device and controlling a level of a first read signal applied to the at least one reference cell in accordance with a result of the detecting of the temperature. The method may also include comparing a first sensing value sensed by applying the first read signal to the at least one reference cell with a second sensing value sensed by applying a second read signal to a selected memory cell among the multiple memory cells.
