| titleOfInvention | The method of alkylthio/alkenyl cysteine sulfoxide is prepared in a kind of fractional crystallization |
| abstract | The method of alkylthio/alkenyl cysteine sulfoxide is prepared in a kind of fractional crystallization, belongs to technical field of compound preparation.Present invention thing order of cysteine or its esters, sodium hydroxide solution, R group (alkyl, alkenyl) being originated adds in dehydrated alcohol thick ACSs is synthesized, ACSs recrystallization is purified, then it is oxidized to ACSOs, obtains the dextrorotation ACSOs of native state through fractional crystallization；By changing R group source thing to synthesize different types of ACSO that allium contains；Separate the enantiomer in racemic modification with Steppecd crystallization, obtained natural A CSOs dextrogyre, there is optical activity.This law yield is high compared with tradition extraction method, and purity is high, it is to avoid complex process that tradition is extracted, and product there is optical activity, physical property is close to natural extract.Product is for effects such as the fields such as health product, pharmaceuticals, antibacterial, anticancer, the blood fat reducing of performance ACSOs, or makes intermediate such as synthesize the active component GIUCOSinoate of allium. |
