  • Patent number: 10913749
    Abstract: The invention provides methods for the synthesis of a halichondrin macrolides 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), catalytic Ring-Closing Olefin Metathesis, or Nozaki-Hiyama-Kishi reaction) to afford a macrocyclic macrolide. The invention also provides compounds useful as intermediates in the synthesis of a halichondrin macrolides and methods for preparing the same.

  • Patent number: 10865011
    Abstract: Provided is a container including a main body, a lid body, and a fixing mechanism that fixes the lid body to prevent the lid body from opening from the main body when the lid body is closed, the fixing being released when the lid body moves to a front side with respect to the main body. Cutouts are formed in side plates of the main body. The container is configured such that, by a rear plate tilting forward toward the cutouts of the side plates, the lid body moves to the front side with respect to the main body and the fixing of the lid body is released, and as the rear plate and a top plate of the lid body form a single plane, the top plate rises and the lid body opens.
