2,2,5,7,8-Pentamethylchroman-6-sulfonyl Chloride CAS 112160-39-1

2,2,5,7,8-Pentamethylchroman-6-sulfonyl chloride feem ntau yog siv los ua ib qho tshwj xeeb sulfonylating reagent thiab hluavtaws intermediate hauv organic thiab tshuaj chemistry. Nws yog ua haujlwm los qhia cov pab pawg tiv thaiv sulfonyl lossis ua kom cov moieties mus rau amines, alcohols, thiab heterocyclic compounds, pab txhawb kev hloov pauv hauv ntau theem kev sib txuas. Cov tshuaj sib xyaw ua ke zoo sib xws nrog cov qauv chroman-based, ua rau nws muaj txiaj ntsig zoo hauv kev npaj cov vitamin E-txog derivatives, antioxidant analogs, thiab ua haujlwm nruab nrab rau kev tshawb fawb tshuaj thiab biochemical. Hauv chav kuaj thiab kev txhim kho, nws yog siv rau hauv kev sib txuas ntawm sulfonamides thiab sulfonate esters qhov twg steric bulk thiab tswj reactivity yuav tsum tau. Nws kuj pom tau siv nyob rau hauv cov qauv-kev tshawb fawb kev sib raug zoo, ua rau cov kws kho mob los hloov cov molecular polarity thiab steric profile thaum tuav lub chroman scaffold.

Lub compound muaj ntau yam zoo stemming los ntawm nws sterically hindered chroman nplhaib thiab reactive sulfonyl chloride functionality. Qhov kev sib xyaw ua ke no tso cai rau sulfonylation zoo thaum muab kev xaiv zoo dua thiab ruaj khov rau cov txiaj ntsig tshwm sim. Nws cov qauv loj tuaj yeem txhim kho kev tiv thaiv rau cov kev tsis txaus siab sab nraud thiab pab kom zoo - kho lub cev muaj zog xws li lipophilicity thiab metabolic stability nyob rau hauv nqes dej molecules. Cov tshuaj reagent nthuav tawm qhov kev ua kom pom tseeb ntawm cov txheej txheem sulfonylation, txhawb nqa cov txiaj ntsig zoo thiab cov txiaj ntsig zoo. Nws cov qauv tsim thiab kev sib raug zoo nrog cov organic solvents yooj yim tuav thiab ntxuav hauv cov khoom siv hluavtaws. Cov txiaj ntsig no ua rau nws muaj txiaj ntsig tshwj xeeb rau kev tsim kho molecule complex thiab kev txhim kho nruab nrab ntawm kev loj hlob.
