Japanese Patent JP2005507418
Kind Code:
A
Abstract:
Disclosed is a method of preparing intermediates required for synthesis of natural carotenoid products using sulfone compounds, which is advantageous in terms of high preparation efficiency due to a relatively simple process. Specifically, there is provided the preparation method of 4-chloro-3-methyl-2-butenylphenylsulfide as a C5-unit compound for lengthening a carbon chain, and di4-chloro-3-methyl-2-butenylsulfide as a C10-unit compound for forming a central polyene moiety. In addition, di4-chloro-3-methyl-2-butenylsulfone as a selective oxide of the di4-chloro-3-methyl-2-butenylsulfide and a preparation method thereof are provided.
