6-trifluoromethyl-2-pyridyl-boronic acid MIDA ester
英文别名
6-Trifluomethyl-2-pyridinylboronic acid MIDA ester;5-methyl-1-[6-(trifluoromethyl)pyridin-2-yl]-2,8-dioxa-5-azonia-1-boranuidabicyclo[3.3.0]octane-3,7-dione
Problem solved: an air-stable 2-pyridyl borane that can effectively couple to a wide range of aryl and heteroaryl halides and pseudohalides has evaded the synthesis community for decades. The discovery that Cu(DEA)(2) powerfully enables palladium-mediated cross-couplings with air-stable boronates 1 has finally provided a general solution to this problem. DEA=diethanolamine, DMF=N,N'-dimethylformamide, Tf=trifluoromethanesulfonyl.

Provided are compounds of formula (I), wherein: ring A and ring B are each independently an optionally substituted 5-6 membered monocyclic aryl or heteroaryl; one of X, Y and W is CH and the two others are N; and Z is H or -C(R1)(R2)(R3). The compounds are inhibitors of isocitrate dehydronenase 2 (IDH2) mutants useful for treating cancer.

A wide range of 2-pyridyl and other difficult-to-access heterocyclic N-methyliminodiacetic acidboronates can be readily prepared from the corresponding bromides via a new method involving direct transligation of 2-heterocyclic trialkoxyborate salts with N-methyliminodiacetic acid (MIDA) at elevated temperatures.
