Title: Innovations of Sangho Koo in Carotenoid Chemistry
Introduction
Sangho Koo is a notable 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
Sangho Koo'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 important moieties 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 is oxidized, and the obtained disulfone compound is combined with a C-10 di(haloallylic) sulfide compound to form a chain compound containing the desired number of carbon atoms. Following this, the diallylic sulfone obtained by oxidation of the diallylic sulfide undergoes a Ramberg-Baklund reaction to form the central triene bond. After the removal of sulfonyl groups, the carotenoid polyene chain compound is obtained.
Another significant patent is the process for preparing 2,7-dimethyl-2,4,6-octatriene-1,8-dial, which starts from an allylic halide. This process includes several steps such as aldehyde protection, conversion to a sulfide, oxidation to an allylic sulfone, followed by a Ramberg-Backlund reaction and hydrolysis.
