Latest Patents
Sau-hoi N John holds a patent for a process titled "Process for preparing higher order cuprate complexes." This invention encompasses a method for preparing higher order cuprate complexes that contain a carbanion, which is essential for forming carbon to carbon bonds in reactions such as epoxide addition. The process involves reacting a first cuprate complex with a stannane, allowing the transfer of the carbanion from the stannane to the first cuprate complex. This innovative approach enables the in situ preparation of a higher order cuprate complex with the desired carbanion for synthetic reactions. The resulting higher order cuprate complexes, particularly those derived from the reaction with 1,2-bis-tri-n-butylstannyl ethylene, are particularly useful for adding to epoxides to create vinyl tin intermediates, which are valuable for preparing omega side chains of prostaglandins.
