Title: Innovations of Minkoo Ji in Carotenoid Chemistry
Introduction
Minkoo Ji is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of carotenoid chemistry, holding a total of 4 patents. His work focuses on innovative processes for synthesizing carotenoid polyene chain compounds, which are essential in various applications.
Latest Patents
Minkoo Ji's latest patents include a process for preparing carotenoid polyene chain compounds and intermediates for preparing the same. This invention provides an intermediate compound used for the synthesis of polyene chain structures, which are crucial components of carotenoid compounds. The process employs an allylic sulfone compound as a starting material, which is reacted with a C-5 sulfide compound to extend the carbon chain. The resultant thio-sulfone compound undergoes oxidation, leading to the formation of a disulfone compound that is combined with a C-10 di(haloallylic) sulfide compound to create a chain compound with the desired number of carbon atoms. The process culminates in the formation of carotenoid polyene chain compounds, particularly lycopene.
Another notable patent is the process for preparing 2,7-dimethyl-2,4,6-octatriene-1,8-dial, which starts from an allylic halide. This process involves several steps, including aldehyde protection, conversion to a sulfide, oxidation to an allylic sulfone, followed by a Ramberg-Backlund reaction and hydrolysis.
