Keywords: copper bisoxazoline phenylglycine polystyrene polymer support cyclopropanation catalyst styrene; enantioselective cyclopropanation catalyst polymer support. We’ll tell you more about this compound (cas:132098-59-0).

Polymer-supported bis(oxazoline) and related ligands have been prepared by grafting and by polymerization methodologies under a variety of conditions. The corresponding Cu complexes have been assayed as catalysts for the cyclopropanation of styrene in the presence of Et azoacetate. Data reveal that insoluble systems prepared by polymerization are much more effective that those prepared by grafting. The best performances, in particular in terms of selectivity, were obtained for tert-butylglycine-derived systems. In some cases, functional resins that are more active, chemoselective, and enantioselective than the corresponding homogeneous analog systems have been obtained. The presence of addnl. functionalities in the polymeric matrix is, in general, detrimental for the performance of the supported catalyst, even if the presence of more flexible cross-linkers enhances the accessibility of the functional sites. The Copper bis(oxazoline) polymeric systems are easily recycled and reused and provide materials of high utility for their use in facilitated chem. synthesis.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Ligand Scaffold Optimization of a Supramolecular Hydrogenation Catalyst: Analyzing the Influence of Key Structural Subunits on Reactivity and Selectivity, published in 2012-12-07, which mentions a compound: 132098-59-0, mainly applied to ligand scaffold optimization supramol hydrogenation catalyst; asymmetric catalysis; asymmetric hydrogenation; rhodium-catalyzed; self-assembled ligands; self-assembly; supramolecular catalysis, Application of 132098-59-0.

Results are reported for the catalytic asym. hydrogenation of two prototypical substrates with a series of more than 150 closely related supramol. catalysts differing in only their ligand/catalyst scaffold. These modular catalysts are constructed from four subunits and vary widely in their reactivity (no reaction to quant. yield) and enantioselectivity (racemic to 96% enantiomeric excess (ee)). Anal. of the ligand/catalyst scaffold optimization data reveals how each subunit contributes to the effectiveness of the modular supramol. catalyst. The results suggest that a balance between key elements of rigidity and flexibility is required for the successful catalysts and, moreover, that this balance is required to enable effective fine-tuning via catalyst scaffold optimization.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle.

The article 《Steric and Electronic Tuning of Chiral Bis(oxazoline) Ligands with 3,3′-Bithiophene Backbone》 in relation to this compound, is published in Journal of Organic Chemistry. Let’s take a look at the latest research on this compound (cas:132098-59-0).

The role played by the electronic properties and the steric features of bis(oxazoline) ligands in the Cu(I)-catalyzed cyclopropanation of styrene effected with Et diazoacetate was investigated. Two pairs of new bis(oxazolines) displaying flexible and atropisomeric 3,3′-bithiophene backbones were synthesized and structurally and electronically characterized. For the first time, the electrochem. oxidative potential was used as a reliable index of the electronic d. on the nitrogen atom of the chelating groups of new and, for comparative purposes, of already known bis(oxazolines). The Cu(I) complexes of the new ligands were prepared, and their enantioselection ability and catalytic efficiency were tested. This investigation suggests that steric factors and catalyst geometrical features are clearly more important than any consideration of the electronic properties of the chiral ligands.

Author is Cichowicz, Nathan R.; Kaplan, Will; Khomutnyk, Yaroslav; Bhattarai, Bijay; Sun, Zhankui; Nagorny, Pavel.

A new scalable enantioselective approach to functionalized oxygenated steroids is described. This strategy is based on chiral bis(oxazoline) copper(II) complex-catalyzed enantioselective and diastereoselective Michael reactions of cyclic ketoesters and enones to install vicinal quaternary and tertiary stereocenters. In addition, the utility of copper(II) salts as highly active catalysts for the Michael reactions of traditionally unreactive β,β’-enones and substituted β,β’-ketoesters that results in unprecedented Michael adducts containing vicinal all-carbon quaternary centers is also demonstrated. The Michael adducts subsequently undergo base-promoted diastereoselective aldol cascade reactions resulting in the natural or unnatural steroid skeletons. The exptl. and computational studies suggest that the torsional strain effects arising from the presence of the Δ5-unsaturation are key controlling elements for the formation of the natural cardenolide scaffold. The described method enables expedient generation of polycyclic mols. including modified steroidal scaffolds as well as challenging-to-synthesize Hajos-Parrish and Wieland-Miescher ketones.
