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.

We report herein a simple alternative method for the asymmetric transfer hydrogenation (ATH) of 1-aryl-3,4-dihydroisoquinolines (1-Ar-DHIQs) that are known to be challenging substrates owing to their poor reactivity. The hydrogenation protocol employs the readily available Cp*Ir(TsDPEN) {where Cp* = pentamethylcyclopentadienyl and TsDPEN = (S,S)-HNCHPhCHPhNTs2?} catalytic complex, 2-propanol and HCOOH/triethylamine mixture as the solvent and hydrogen donor, and anhydrous phosphoric acid as an inexpensive additive. The series of examined substrates shows a favorable tolerance to various functional groups. Unlike 1-alkyl-DHIQs, where the enantiomeric excess (ee) starkly changes during the course of hydrogenation, 1-Ar-DHIQs exhibit a constant ee value, which makes the method practical and useful for the production of fine chemicals containing the 1,2,3,4-tetrahydroisoquinoline motif.

Stereoselective synthesis of 1-substituted 1,2,3,4-tetrahydro-beta-carbolines by asymmetric electrophilic alpha-amidoalkylation reactions

An efficient procedure for the asymmetric synthesis of 1-substituted1,2,3,4-tetrahydro-9-methyl-beta-carbolines based on asymmetric electrophilic alpha-amidoalkylation reactions is described. Stereoselective addition of various organometallic reagents to a chiral N-acyl-beta-carbolinium ion gave the corresponding 1-substituted 1,2-dihydro-beta-carbolines in high yields and very good to excellent diastereomeric ratios. Catalytic hydrogenation followed by the removal of the chiral auxiliary via reductive cleavage of the amide bond proceeded with complete conservation of the absolute configuration at the newly created stereocenter leading to 1-substituted 1,2,3,4-tetrahydro-9-methyl-beta-carboline derivatives in high yields. Their absolute stereochemistry was proven by X-Ray analysis. The 1-phenyl-substituted 1,2,3,4-tetrahydro-beta-carbolines were evaluated for their affinity to the PCP binding site of the NMDA receptor.
