4-Chloro-3-methyl-2-butenylphenyl sulfide, di (4-chloro-3-methyl-2-butenyl) sulfide and di (4-chloro-3-methyl-) for the synthesis of natural carotenoid products Preparation of 2-butenyl) sulfone |
| abstract |
Disclosed is a method for preparing intermediates necessary for the synthesis of natural carotenoid products using sulfone compounds, which is advantageous in terms of high preparation efficiency due to the relatively simple process. Specifically, 4-chloro-3-methyl-2-butenylphenyl sulfide as a C5-unit compound for extending a carbon chain, and di (C10-unit compound as a central polyene moiety) A process for the preparation of 4-chloro-3-methyl-2-butenyl) sulfide is provided. Also provided are di (4-chloro-3-methyl-2-butenyl) sulfone as a selective oxide of di (4-chloro-3-methyl-2-butenyl) sulfide and a method for its preparation. |
