Diverse secondary C(sp3)-H bond functionalization via site-selective trifluoroacetoxylation of aliphatic amines.


ABSTRACT: We describe a coinage-metal-catalyzed site-selective oxidation of secondary C(sp3)-H bonds for aliphatic amine substrates. Broad amine scope, good functional compatibility and late-stage diversification are demonstrated with this method. The steric demand of the ?-substituents controlled diastereoselectivities under this catalytic system. The site selectivity favors secondary C(sp3)-H bonds over tertiary ones underscoring the unique synthetic potential of this method.

We describe a coinage-metal-catalyzed site-selective oxidation of secondary C(sp<sup>3</sup>)-H bonds for aliphatic amine substrates. Broad amine scope, good functional compatibility and late-stage diversification are demonstrated with this method. The steric demand of the β-substituents controlled diastereoselectivities under this catalytic system. The site selectivity favors secondary C(sp<sup>3</sup>)-H bonds over tertiary ones underscoring the unique synthetic potential of this method. ...[more]
