Cov Ntawv Thov
1. Nruab nrab hauv cov khoom siv hauv nruab nrog cev
4-Bromo-1,2- (Methylenedioxy) Benzene tau siv dav ua ib qho nrab ntawm cov synthesis ntawm ntau qhov nyuaj olecules. Nws lub nplhaib aromatic nrog reflective hloov (br thiab methylenedioxy) ua rau nws muaj txiaj ntsig zoo hauv ntau kauj ruam tshuaj synthesis.
Hloov pauv cov kev cai: Lub bromine atom ua raws li cov pab pawg tsis tau (piv txwv li, ua kom tiav), ua rau kev tsim cov roj carbon tshiab.
Cov pab pawg ua haujlwm: cov methylenedioxy pab pawg muab cov khoom siv nruj thiab tshuab hluav taws xob uas muaj txiaj ntsig zoo hauv kev sib txuas, heterocycles, thiab cov tebchaw bioaction.
2. Kws Tshuaj Nruab Nrab
Nws yog lub tsev tseem ceeb hauv kev lag luam hauv cov tshuaj rau cov synthesis ntawm ntau cov molecules.
Cov khoom xyaw ntawm cov khoom xyaw (APIs): Nws yog siv hauv kev tsim kho ntawm kws tshuaj uas ua kom pom CNS kev ua si, tiv thaiv cov teeb meem, lossis cov antimicrobial.
Precursor rau benzodioxole-raws li cov tshuaj: lub methylenioxybenzene scaffolden tau pom nyob rau hauv ntau cov kws tshuaj molecules, xws li cov uas muaj kev cuam tshuam nrog lub hlwb.
3. Agnaphical synthesis
4-Bromo-1,2- (Metylenedioxy) Benzene tseem muaj txiaj ntsig zoo nyob rau hauv kev muaj kev lag luam agochemical.
Precursor rau tshuaj tua kab los yog tshuaj tua kab mob: nws pab txhawb rau cov hluavtaws ntawm cov tshuaj lom neeg muaj tshuaj tua kab mob nrog tshuaj tua kab mob.
Kev tshuaj zoo rau cov qoob loo tiv thaiv: Siv hauv kev tsim cov duab uas muaj ntxhiab pleev thaiv uas tsis muaj zog thiab ib puag ncig ruaj khov.
4. Tshawb nrhiav thiab kev txhim kho
Nws yog feem ntau siv nyob rau hauv kev kawm thiab kev tshawb fawb rau kev tsim cov kev xav tau tshiab thiab txoj hauv kev tshiab.
Cov qauv sib txuas: pab tau hauv kev sim thiab ua kom cov tshuaj tiv thaiv kom zoo rau cov kev hloov pauv halyl.
Cov qauv-kev ua si sib raug zoo (SAR) Kev Kawm Ntawv: Ua cov tsev qiv ntawv hluav taws xob loj dua, nws yog siv los ntsuas kev ua haujlwm biological ntawm methylenedioxy-hloov cov arenes.
Cov txiaj ntsig
1. Versatile pawg ua haujlwm
Lub bromine atom yog reactive nyob rau hauv palladium-catalyzed coupling kev tawm tsam.
Cov methylenedioxy pab pawg ruaj khov lub nplhaib muaj ntxhiab thiab tuaj yeem txhim kho kev ua yeeb yam hauv qhov kawg.
Lub sijhawm no ntawm electrophilic (br) thiab electron-donating (och2o) pab pawg ua kom muaj hluav taws xob dav.
2. Qhov tseem ceeb hauv nruab nrab rau cov muaj txiaj ntsig zoo sib txuas
Muab txoj hauv kev muaj txiaj ntsig zoo rau cov txiaj ntsig heterocycles, kws tshuaj, thiab cov ntxhiab derivatives nrog biological cov yam ntxwv.
3. Ruaj khov thiab yooj yim tuav
Khoom nyob ntawm chav tsev kub, tso cai rau kev cia khoom yooj yim, hnyav, thiab thauj.
Chemically ruaj khov nyob rau hauv lub chaw kuaj ib txwm muaj.
4. Siv dav hauv cov hluavtaws niaj hnub no
Txhawb nqa C-C raug khi ua ke, lub pob kws ntawm cov organic organic.
Nquag suav nrog hauv cov qauv synthetic rau kev tsim muaj ntau haiv neeg aromatic tebchaw.
Tag
4-Bromo-1,2- (methylenedioxy) benzene (CASE 2635-135-135-135-135-135-135-135-135, yog kev siv tshuaj coob heev nyob thoob plaws lub puab luj teg. Nws cov pab pawg ua haujlwm muab cov versatility ntau rau ntau yam kev hloov tshuaj lom, tshwj xeeb hauv palladium-catally-cathlel-catepling thiab cov ntxhiab hloov tau. Nrog nws ruaj khov, reassivity, thiab tsim cov nqi hluav taws xob hauv kev sib txuas ua ke, cov kab ke no tseem ceeb tshaj plaws hauv kev siv tshuaj tseem ceeb hauv kev tshawb fawb niaj hnub thiab kev tshawb fawb.
