Bifunctional iron complexes: Efficient catalysts for C=O and C=N reduction in water

The application of bifunctional iron complexes for the hydrogenation of polarized C=X bonds is reported. Two modified Knoelker complexes bearing ionic fragments were synthesized and fully characterized. With these well-defined complexes, the reaction proceeded under mild conditions in pure water, and various alcohols and amines were isolated in good yields. Compared with hydrogenation in organic solvents, better reactivities were observed. Is this the iron age? Well-defined iron-complex-catalyzed reduction of aldehydes, ketones, and imines using molecular hydrogen in water is presented. Under mild conditions, good yields for a broad range of substrates are achieved.

Ferritin encapsulation of artificial metalloenzymes: Engineering a tertiary coordination sphere for an artificial transfer hydrogenase

Ferritin, a naturally occuring iron-storage protein, plays an important role in nanoengineering and biomedical applications. Upon iron removal, apoferritin was shown to allow the encapsulation of an artificial transfer hydrogenase (ATHase) based on the streptavidin-biotin technology. The third coordination sphere, provided by ferritin, significantly influences the catalytic activity of an ATHase for the reduction of cyclic imines.

Isoquinoline-N-Boranes as Precursors to Substituted Tetrahydroisoquinolines

A new approach to the syntheses of 1,2-disubstituted 1,2,3,4-tetrahydroisoquinolines from isoquinoline-N-boranes is described.The method is a “one-pot” operation in which substituents are introduced consecutively as electrophiles and nucleophiles with accompanying reduction of the heterocyclic ring.This procedure differs from the classical ones in that both requisite rings are present in the starting material and thus avoids the inefficient cyclizations of phenethylamine derivatives when unactivated substrates would be required.The synthetic utility of this process is demonstrated with several examples including the alkaloids carnegine and hydrohydrastinine.

Noncompetitive NMDA Antagonists: A novel synthesis of 1-phenyltetrahydro-3-benzazepines

The key step in the synthesis of the pharmacologically interesting l-phenyltetrahydro-3-benzazepine skeleton is the Michael addition of (2-lithiophenyl)acetaldehyde acetals, which are generated in situ upon treatment of the bromo acetals 5a,b with n-butyllithium, to beta-nitrostyrene (6). The reductive ring closure of the nitro acetals 7a,b succeeded with zinc dust and hydrochloric acid to give the 3-benzazepines 11a,b in good yields. The unsubstituted 3-benzazepine 11a showed a considerable affinity for the phencyclidine binding site of the NMDA receptor (K(i) = 6.41 muM), whereas donor substituents in the aryl moiety (11b,c) reduce the affinity for the NMDA receptor.
