The biochemical characterization of three imine-reducing enzymes from Streptosporangium roseum DSM43021, Streptomyces turgidiscabies and Paenibacillus elgii

Recently imine reductases (IREDs) have emerged as promising biocatalysts for the synthesis of a wide variety of chiral amines. To promote their application, many novel enzymes were reported, but only a few of them were biochemically characterized. To expand the available knowledge about IREDs, we report the characterization of two recently identified (R)-selective IREDs from Streptosporangium roseum DSM43021 and Streptomyces turgidiscabies and one (S)-selective IRED from Paenibacillus elgii. The biochemical properties including pH profiles, temperature stabilities, and activities of the enzymes in the presence of organic solvents were investigated. All three enzymes showed relatively broad pH spectra with maximum activities in the neutral range. While the (R)-selective IREDs displayed only limited thermostabilities, the (S)-selective enzyme was found to be the most thermostable IRED known to date. The activity of this IRED proved also to be most tolerant towards the investigated co-solvents DMSO and methanol. We further studied activities and selectivities towards a panel of cyclic imine model substrates to compare these enzymes with other IREDs. In biotransformations, IREDs showed high conversions and the amine products were obtained with up to 99?% ee. By recording the kinetic constants for these compounds, substrate preferences of the IREDs were investigated and it was shown that the (S)-IRED favors the transformation of bulky imines contrary to the (R)-selective IREDs. Finally, novel exocyclic imine substrates were tested and also high activities and selectivities detected.

STRUCTURE AND PROPERTIES OF 8-AZASTEROIDS SYNTHESIZED BY REGIO- AND STEREOSELECTIVE ANNELATION OF 3,4-DIHYDROISOQUINOLINES BY ASYMMETRIC 2-ACYL-1,3-CYCLOHEXANEDIONES

It was found that annelation of 3,4-dihydroisoquinolines by 2-acyl-1,3-cyclohexanediones takes place regio- and stereoselectively, leading to C(11)- and C(17)-substituted derivatives of the 8-aza-D-homogonane series with a trans-disposition of the substituents (Me, Br, Cl, COOMe) at the above positions relative to the angular substituent (H, Me) at C(9). It was shown that the C(17)-halogen and methoxycarbonyl derivatives exist in crystals in the form of one stereoisomer, while in solutions as a mixture of stereoisomers, caused by a keto-enol tautomerism of the C(17a)-carbonyl. In solutions of acids, these derivatives exist in N(8)-…-C(17a) immonium-enol form, as one stereoisomer. It was found that the C(11)-methyl derivatives are obtained in the form of two restrained conformers with respect to ring C, which on boiling are reduced to one conformer. The assignment of the enol regiomers of 4-substituted 2-acetyldimedones has been carried out.

Recent Progress in Heterogeneous Asymmetric Hydrogenation of C=O and C=C Bonds on Supported Noble Metal Catalysts

The ease of separation, simple regeneration, and the usually high stability of solid catalysts facilitating continuous production processes have stimulated the development of heterogeneous asymmetric hydrogenation catalysis. The simplest and so far most promising strategy to induce enantioselectivity to solid metal catalysts is their modification by chiral organic compounds, as most prominently represented by the cinchona-modified Pt and Pd catalysts for the asymmetric hydrogenation of activated C=O and C=C bonds. In this Review, we provide a systematic account of the research accomplished in the past decade on noble metal-based heterogeneous asymmetric hydrogenation of prochiral C=O and C=C bonds, including all important facets of these catalytic systems. The advances made are critically analyzed, and future research challenges are identified.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C11H13NO2, you can also check out more blogs about3382-18-1
