Applicazioni

It is a reagent of choice for assignment of absolute configuration of chiral primary amines by 1H NMR, giving better results than Mosher's acid ((R)-(+)-?-Methoxy-?-(trifluoromethyl)­phenyl­acetic acid. αR)-α-[[(1,1-Dimethylethoxy)carbonyl]amino]-benzeneacetic Acid is D-(+)-2-Phenylglycine with Boc protecting group. (αR)-α-[[(1,1-Dimethylethoxy)carbonyl]amino]-benzeneacetic Acid is used as part of a catalyst combination to catalyze regioselective [4 + 2] cycloadditions of β-substituted cyclic enones and polyconjugated malononitriles. It can also be used to catalyze stereoselective preparation of polyfunctional nitrocyclohexene carboxaldehydes.

Note

Store away from oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
