权利人:THE TRUSTEES OF BOSTON COLLEGE
摘要:Radical cascade reactions enabling sequence-controlled ring-closing polymerization and ring-opening polymerization for the controlled synthesis of polymers with complex main-chain structures are provided. Facile syntheses leading to low-strain macrocyclic monomers consisting of the ring-opening triggers and extended main-chain structures are also provided. The present disclosure further provides methods for excellent control over polymer molecular weights and molecular weight distributions and high chain-end fidelity allows for the preparation of polymeric systems with well-defined architectures. Further provided are the general nature of the radical cascade-triggered transformations in polymer chemistry, and its application to the synthesis of polymers with diverse main-chain structural motifs with tailored functions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

标题:Method for the Synthesis of Ionizable Lipids Using a Doubly Alkylated Intermediate

摘要:Provided herein is a method for the preparation of ionizable, cationic amino lipids using a doubly alkylated nucleophilic intermediate to produce a ketone. The ketone, or a corresponding alcohol, is subjected to one or more synthesis steps to add an ionizable moiety thereto. The method can be advantageously employed for the synthesis of unsymmetrical analogues of the above lipids that would be considerably more difficult to make by alternative strategies. The method can also be used to prepare symmetrical ionizable, cationic amino lipids with fewer steps and/or with the use of fewer hazardous chemicals than known synthesis methods.

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).
