A process for efficiently producing, through few steps either a xanthine oxidase inhibitor, which is a therapeutic agent for hyperuricemia, or an intermediate therefore. The process is a novel coupling process which comprises subjecting a compound represented by formula (1) to coupling reaction with a compound represented by formula (2) in the presence of a transition metal compound to thereby obtain a compound represented by formula (3).
Provided herein are palladium-mediated coupling reactions useful in the preparation of ketone-containing organic molecules. The provided methods can be used for the preparation of natural products and pharmaceutical agents, including Eribulin, halichondrins, and analogs thereof. The present invention also provides novel halichondrin analogs which can be prepared via the palladium-mediated coupling reactions. The novel halichondrin analogs can be used in the prevention and/or treatment of diseases or conditions (e.g., proliferative diseases such as cancer).
