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.

An efficient synthesis of polyynyl and polyynediyl complexes of ruthenium(II)

The fluoride-induced desilylation of trimethylsilyl-substituted alkynes and polyynes and subsequent reactions with RuCl(PPh3)2Cp have been used to synthesize complexes containing unsaturated chains containing up to six carbons. Reactions with Co2(CO)8 or tetracyanoethene have been further used to characterise the products.

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

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).

16-electron (arene)ruthenium complexes with superbasic bis(imidazolin- 2imine) ligands and their use in catalytic transfer hydrogenation

The ligands N,N’-bis(l,3,4,5-tetramethylimidazolin-2-ylidene)-l,2- ethanediamine (BLMe) and N,N-bis(l,3-diisopropyl-4,5- dimethylimidazolin-2-ylidene)-l,2-ethanediamine (BLIPr) react with [(eta5-C5Me5)RuCl]4 to afford cationic 16electron half-sandwich complexes [(eta5-C 5Me5)Ru(BLR)]+ (R = Me, 3; R = iPr, 4), which resist coordination of the chloride counterion because of the strong electron-donating ability of the diimine ligands. Upon reaction with [(eta6-C6H6)RuCl2]2 or [(eta6-C10H14)RuCl2]2, these ligands stabilize dicationic 16electron benzene and cymene complexes of the type [(eta6C6H6)Ru(BLR)] 2+ (R = Me, 5; R = iPr, 6) and [(eta6-C 10H14)Ru(BLR)]2+ (R = Me, 7; R = iPr, 8). The X-ray crystal structure of [5]C12 reveals the absence of any direct Ru-Cl interaction, whereas a long Ru-Cl bond, supported by two CH-C1 hydrogen bonds, is observed for [(6)Cl]Cl in the solid state. Treatment of the dichlorides of 6 and 8 with NaBF4 affords [6](BF4) 2 and [8](BF4)2, which are composed of individual dications and tetrafluoroborate ions with no direct Ru-F interaction, All complexes catalyze the transfer hydrogenation of acetophenone in boiling 2-propanol Wiley-VCH Verlag GmbH & Co.

Dialkylamino cyclopentadienyl ruthenium(II) complex-catalyzed alpha-alkylation of arylacetonitriles with primary alcohols

Aminocyclopentadienyl ruthenium complexes, [(eta5-C 5H4NMe2)Ru(PPh3)2(CH 3CN)]+BF4- and [(eta5- C5H4NEt2)Ru(PPh3) 2(CH3CN)]+BF4-, are moderately active catalysts for alpha-alkylation of arylacetonitriles with primary alcohols; on the other hand, the analogous unsubstituted cyclopentadienyl ruthenium complex [(eta5-C5H 5)Ru(PPh3)2(CH3CN)] +BF4- shows very low catalytic activity. On the basis of experimental results and theoretical calculations, rationalization for the much higher catalytic activity of the aminocyclopentadienyl complexes over that of the unsubstituted Cp complex is provided. In the catalytic systems with the former, it is possible to regenerate the active solvento complexes via protonation of the metal hydride intermediates and subsequent ligand substitution; this process is, however, very nonfacile in the catalytic system with the latter.
