Catalysts for the asymmetric transfer hydrogenation of various ketones from [3-[(2S)-2-[(diphenylphosphanyl)oxy]-3-phenoxypropyl]-1-methyl-1H-imidazol-3-ium chloride] and [Ru(eta6-arene)(mu-Cl)Cl]2, Ir(eta5-C5Me5)(mu-Cl)Cl]2 or [Rh(mu-Cl)(cod)]2

The combination of [3-[(2S)-2-[(diphenylphosphanyl)oxy]-3-phenoxypropyl]-1-methyl-1H-imidazol-3-ium chloride] with [Ru(eta6-arene)(mu-Cl)Cl]2, Ir(eta5-C5Me5)(mu-Cl)Cl]2 or [Rh(mu-Cl)(cod)]2, in the presence of KOH/isoPrOH, has been found to generate catalysts that are capable of enantioselectively reducing alkyl, aryl ketones to the corresponding (R)-alcohols. Under optimized conditions, when the catalysts were applied to the asymmetric transfer hydrogenation, we obtained the secondary alcohol products in high conversions and enantioselectivities using only 0.5 mol% catalyst loading. In addition, [3-[(2S)-2-{[(chloro(?4-1,5-cyclooctadiene)rhodium)diphenyl phosphanyl] oxy}-3-phenoxypropyl]-1-methyl-1H-imidazol-3-ium chloride], (6) complex is much more active than the other analogous complexes in the transfer hydrogenation. Catalyst 6 acts as excellent catalysts, giving the corresponding (R)-1-phenyl ethanol in 99% conversion in 30 min (TOF ? 396 h?1) and in high enantioselectivity (92% ee).

Recent Advances in Cascade Reactions Initiated by Alcohol Oxidation

In this review, we attempt to answer the question: how can we construct complex functionalized molecules with significant added value from cheap and readily available alcohols in the simplest and most efficient manner? Accordingly, recent developments (mainly from the last five years) in the field of one-pot multiple transformations of alcohols are overviewed in terms of process simplification and optimization; sustainability; and atom, bond, step, and redox economy. Particular attention is paid to chemo- and stereoselective transformations with specific formation of particular bonds and configurations, leaving other parts of substrates unchanged.

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.Product Details of 114615-82-6, you can also check out more blogs about114615-82-6

Enantioselective Total Synthesis of Erogorgiaene: Applications of Asymmetric Cu-Catalyzed Conjugate Additions of Alkylzincs to Acyclic Enones

The first enantioselective synthesis of erogorgiaene (1), an inhibitor of mycobacterium tuberculosis, is disclosed. The total synthesis highlights the utility of asymmetric conjugate additions (ACA) of alkylzincs to acyclic alpha,beta-unsaturated ketones catalyzed by peptidic phosphine ligands and (CuOTf)2¡¤C6H6. Moreover, several critical attributes of this catalytic C-C bond-forming reaction are illustrated in the context of the total synthesis; these include the significance of various structural features of the amino acid-based chiral ligands and the chiral ligand’s effectiveness in reactions involving achiral and chiral substrates. In addition, the total synthesis showcases some of the special properties of nonphosphine Ru complex 3 as a highly effective catalyst for olefin cross-metathesis.

Precision ADMET polyolefins containing dithiane: Synthesis, thermal properties, and macromolecular transformation

1,3-Dithiane and its derivatives are widely used as powerful acyl anion equivalent to a range of useful transformations that are needed in the synthesis of natural products. In this work, a series of polyolefins containing pendant dithiane groups have been designed and synthesized via acyclic diene metathesis polymerization (ADMET) polymerization and subsequent hydrogenation. The structures of these polymers were characterized by 1H NMR, 13C NMR, and FT-IR, and successful incorporation of the dithiane groups was proved. With different contents of the dithiane moieties, these ADMET polymers exhibited distinct thermal properties different from each other as evidenced by differential scanning calorimetry and thermal gravimetric analysis. The dithiane units in the ADMET polymer with 20 methylene carbons between the adjacent dithiane groups were transformed into thiol groups via reaction with Bu3SnH. This work provided a convenient route to synthesize polyethylene with pendant thiol groups that are evenly distributed in the chain.
