Cytochrome P-450-catalyzed hydroxylation and carboxylic acid ester cleavage of Hantzsch pyridine esters.

Cytochrome P-450 (P-450)-catalyzed oxidation of 2,6-dimethyl-4-phenyl-3,5-pyridinedicarboxylic acid diethyl ester gives rise to 2,6-dimethyl-4-phenyl-3,5-pyridinedicarboxylic acid monoethyl ester and to 2-hydroxymethyl-6-methyl-4-phenyl-3,5-pyridinedicarboxylic acid diethyl ester, identified in this work. A pyridine hydroxymethyl diester of the sort of the latter compound is novel; under acidic...

1 Lewis Acid – Brønsted Base Catalysis

From the synthetic point of view, organic synthesis via catalytic processes offers many benefits. Catalysis frequently obviates the excessive use of the activating reagents and associated tedious purification processes, thereby offering more environmentally benign synthetic processes. Furthermore, the specific activation mode of a catalyst allows for highly chemoselective transformations that a...

Hydroamination reactions by metal triflates: Brønsted acid vs. metal catalysis?

Catalytic hydroamination reactions involving the addition of carboxamides (X = CO), carbamates (X = CO(2)) and sulfonamides (X = SO(2)) to unactivated C=C bonds are briefly reviewed. Development in this field of catalytic research is briefly charted, followed by a discussion of possible mechanisms, including arguments to support the operation of both metal and Brønsted acid catalysis in these s...

Brønsted acid differentiated metal catalysis by kinetic discrimination.

A Brønsted acid differentiated metal catalyzed hydrogenation has been developed. A combinatorial variation of chiral triflylamides with achiral metal complexes results in a highly active catalyst for the asymmetric reduction.

Chiral Brønsted acid-catalyzed allylboration of aldehydes.

The catalytic enantioselective allylation of aldehydes is a long-standing problem of considerable interest to the chemical community. We disclose a new high-yielding and highly enantioselective chiral Brønsted acid-catalyzed allylboration of aldehydes. The reaction is shown to be highly general, with a broad substrate scope that covers aryl, heteroaryl, alpha,beta-unsaturated, and aliphatic ald...
