Sterman, Andrej;Kosmrlj, Janez;Zigart, Nina;Gobec, Stanislav;Sosic, Izidor;Casar, Zdenko research published 《 Catalytic Approach to Diverse α-Aminoboronic Acid Derivatives by Iridium-Catalyzed Hydrogenation of Trifluoroborate-Iminiums》, the research content is summarized as follows. Structurally diverse benzyl protected trifluoroborate-ammoniums were prepared in good to high yields by an efficient hydrogenation of corresponding trifluoroborate-iminiums using Crabtree’s catalyst. Subsequent N- and B-deprotections were demonstrated on selected examples to provide several α-aminoboronic acids. Preliminary experiments on asym. version of the reaction indicated a correlation between E/Z-ratio in the trifluoroborate-iminium substrate and enantioselectivity. The broad scope, operational simplicity and efficiency of the presented method imply its high potential for a facile access to libraries of α-aminoboronic acid derivatives that can be used in medicinal chem. applications and beyond.

Shi, Yongjia;Yang, Yuhuan;Xu, Senmiao research published 《 Iridium-Catalyzed Enantioselective C(sp³)-H Borylation of Aminocyclopropanes》, the research content is summarized as follows. Transition-metal-catalyzed regio- and stereo-controllable C-H functionalization remains a formidable challenge in asym. catalysis. Herein, we disclose the first example of iridium-catalyzed C(sp³)-H borylation of aminocyclopropanes by using simple imides as weakly coordinating directing groups under mild reaction conditions. The reaction proceeded via a six-membered iridacycle, affording a vast range of chiral aminocyclopropyl boronates. The current method features a broad spectrum of functional groups (36 examples) and high enantioselectivities (up to 99%). We also demonstrated the synthetic utility by a preparative scale C-H borylation, C-B bond transformations, and conversion of the directing group.

Skovpin, Ivan V.;Kovtunova, Larisa M.;Nartova, Anna V.;Kvon, Ren I.;Bukhtiyarov, Valerii I.;Koptyug, Igor V. research published 《 Anchored complexes of rhodium and iridium for the hydrogenation of alkynes and olefins with parahydrogen》, the research content is summarized as follows. Several catalysts synthesized by covalently binding Rh and Ir complexes to NH₂^– and PPh₂^– functional groups of the linker chains on the functionalized silica gel surface were compared in gas-phase hydrogenation of propyne and propene. Their stability, activity and product selectivity were evaluated. Furthermore, the use of parahydrogen in the reaction provided useful mechanistic information by delivering nuclear spin hyperpolarization of the reaction products with the associated enhancement of their NMR signals. In contrast to Rh-based catalysts which showed a pronounced tendency to reduction, for Ir-based catalysts an XPS anal. did not reveal any indication of the formation of a metal phase under reducing conditions upon hydrogenation of propyne or propene at 120°C. Catalysts with a π-acceptor ligand PPh₂^– demonstrated greater activity in the gas-phase hydrogenation of propyne/propene in comparison with σ-donor ligand NH₂^–. Furthermore, NMR signal enhancements of up to ca. 700- (Rh) and 800-fold (Ir) were achieved. Remarkably, the Ir metal complex bound via the phosphine moiety demonstrated high stability in gas-phase hydrogenation of propyne along with high catalytic activity and pairwise H₂ addition selectivity, yielding substantial quantities of strongly hyperpolarized propene.

Oscar C.;Rangel-Garcia, Jesus;Cristobal, Crispin;Lopez, Jorge A. research published 《 Oxidative Coordination versus C³-C(O)Me Bond Cleavage in Acetylacetonate Iridium Complexes》, the research content is summarized as follows. Iridabicycles [Ir{κ³-N,C,O-(pyC(H):C(C(O)Me))₂}(Cl)(L-L)](L-L=cod (cod=1,5-cyclooctadiene), 1a; bipy (bipy=2,2′-bipyridine), 1b) have been obtained by oxidative coordination of 3-(pyridine-2-yl-methylene)pentane-2,4-dione L1, to the complexes [{Ir(μ-Cl)(cod)}₂] and [{Ir(μ-Cl)(coe)₂}₂] (coe=cis-cyclooctene), the latter in the presence of bipy. Remarkably, cleavage of the C³-C(O)Me bond of L1 has instead been achieved in the reaction with [Ir(Cl)(dmb)₂] (dmb=2,3-dimethylbutadiene), yielding a compound formulated as [Ir{κ²-N,C-(pyC(H)C(C(O)Me))}(CO)(μ-Cl)(Me)]₂, 2. Treatment of dimer 2 with DMSO or PMe₃ produced the complexes[Ir{κ²-N,C-(pyC(H)C(C(O)Me))}(CO)Cl(Me)L] (L=DMSO, 3a; PMe₃, 3b). Plausible mechanisms for the reactions leading to complexes 1 and 2 are proposed by means of DFT calculations

The synthesis of a family of P-stereogenic phosphinooxazoline iridium catalysts from L-threonine Me ester and their use in the asym. hydrogenation of N-Boc-2,3-diarylallyl amines, achieving very high enantioselectivity was reported. Furthermore, the synthetic utility of the 2,3-diarylpropyl amines obtained was demonstrated by their transformation to 3-aryl-tetrahydroquinolines and 4-benzyl-tetrahydroisoquinolines, which had not yet been obtained in an enantioselective manner by direct reduction of the corresponding aromatic heterocycles. This strategy allowed the preparation of these types of alkaloids with the highest enantioselectivity reported up to date.
