CAS Nr .: 109737-57-7 6-Methyl-2-phenyl-1,3,6,2-dioxazaborocane-4,8-dione

6-Methyl-2-phenyl-1,3,6,2-dioxazaborocane-4,8-dione yog ib qho organoboron reagent nrog cov mis molecular ntawm C₁₁H₁₂BNO₄. Nws cov qauv tshuaj muaj ib lub nplhaib benzene thiab ib pawg methyliminodiacetate (MIDA), thiab nws belongs rau derivative esters ntawm phenylboronic acid. CAS Nr .: 109737-57-7

Kev siv:

Raws li qhov ruaj khov boronation reagent, 6-Methyl-2-phenyl-1,3,6,2-dioxazaborocane-4,8-dione yog siv dav hauv Suzuki-Miyaura coupling cov tshuaj tiv thaiv. Nws tuaj yeem qhia phenylboronic acid pawg nyob rau hauv cov mob me me, zam qhov teeb meem ntawm oxidation yooj yim lossis hydrolysis ntawm cov tshuaj boric acid. Nws cov qauv MIDA ester tuaj yeem txhim kho kev xaiv cov tshuaj tiv thaiv thiab substrate compatibility, thiab tsim nyog rau cov synthesis ntawm complex molecules (xws li tshuaj intermediates thiab cov khoom ntuj).

Txoj Kev Npaj:
Ib txoj hauv kev siv hluavtaws yog los ua ke phenylboronic acid methyliminodiacetate siv ester pauv cov tshuaj tiv thaiv ntawm imines. Cov txheej txheem synthesis tshwj xeeb suav nrog:
Reacting methyl p-tolylboronate nrog ethyl nitroso-2-acetamidoacetate los tsim ethyl imino-2-(p-tolylboronic acid) acetate.
Reacting ethyl imino-2-(p-tolylboronic acid) acetate nrog lwm esterifying reagent, xws li ethyl bromoacetate los yog n-butanol, los tsim cov khoom kawg 6-Methyl-2-phenyl-1,3,6,2-dioxazaborocane-4.,8-
