摘要:The present invention provides methods for the synthesis of ketones involving a Ni/Zr-mediated coupling reaction. The Ni/Zr-mediated ketolization reactions can be used in the synthesis of halichondrins (e.g., halichondrin A, B, C; homohalichondrin A, B, C; norhalichondrin A, B, C), and analogs thereof. Therefore, the present invention also provides synthetic methods useful for the synthesis of halichondrins, and analogs thereof. Also provided herein are compounds (i.e., intermediates) useful in the synthesis of halichondrins, and analogs thereof. In particular, the present invention provides methods and compounds useful in the synthesis of compound of Formula (H3-A).

摘要:The present disclosure provides for enzymatic polymerization to produce polyester resins suitable for use in manufacturing toners. In embodiments, crystalline copolymers, which are polyesters, may be synthesized from lactones, cyclic anhydrides, cyclic carbonates, and combinations thereof. These crystalline copolymers, in turn, may be utilized in the synthesis of toner particles.
