Asymmetric epoxidation of α,β-unsaturated ketones catalyzed by rare-earth metal amides RE[N(SiMe3)2]3with chiral TADDOL ligands

The catalytic asymmetric epoxidation of α,β-unsaturated ketones by tert-butylhydroperoxide (TBHP) has been well established using rare-earth metal amides RE[N(SiMe3)2]3 (RE = La(1), Nd(2), Sm(3), Y(4), Yb(5)) with chiral TADDOL ligands. It was found that

Application of chiral TADDOL ligand and rare earth metal amide in combined catalysis of asymmetric reaction

The invention relates to application of chiral TADDOL ligand and rare earth metal amide in combined catalysis of asymmetric epoxidation reaction of chalcone compounds. According to the application, alpha, beta-unsaturated ketone shown in a formula (1) and tert-butyl hydroperoxide react in the presence of organic alkali under the combined catalytic action of a chiral TADDOL ligand shown in a formula (3) and rare earth metal amide in an anhydrous, oxygen-free and protective atmosphere to obtain the chiral epoxy compound shown in the formula (2) after the reaction is completed, wherein R1 is selected from hydrogen, alkyl, halogen, alkoxy, trifluoromethyl, nitro or cyano, R2 is selected from phenyl, substituted phenyl, naphthyl, furyl or thienyl; R3 and R4 are respectively and independently selected from alkyl, phenyl or R3 and R4 and carbon atoms connected with R3 and R4 form naphthenic base; Ar is phenyl, substituted phenyl, biphenyl or naphthyl; the molecular formula of the rare earth metal amide is RE [N (SiMe3) 2] 3. The method has the advantages of wide substrate application range, high yield and high enantioselectivity.

Crown-ether-modified cyclic dipeptides as supramolecular chiral catalysts

With the objective to develop supramolecular catalysts for useful chemical transformations, we report here a rapid and efficient solid-phase synthesis of novel cyclic dipeptides (crown-CDPs) with a diversity of L-DOPA derived crown ether substituents and

Visible-Light-Driven Epoxyacylation and Hydroacylation of Olefins Using Methylene Blue/Persulfate System in Water

A visible-light-driven strategy for hydroacylation and epoxyacylation of olefins in water using methylene blue as photoredox catalyst and persulfate as oxidant is reported. In this unprecedented unified approach, two different transformations are accomplished using only one set of reagents. The method has a broad scope spanning a range of aromatic and aliphatic aldehydes as well as conjugated and nonconjugated olefins to deliver ketones and epoxyketones from abundant and inexpensive chemical feedstocks.

Revisiting the Juliá-Colonna enantioselective epoxidation: Supramolecular catalysis in water

We describe an efficient epoxidation process leading to chiral epoxyketones using the reusable homo-oligopeptide poly-l-leucine (PLL) in pure water, without any organic co-solvent. A range of substituted epoxyketones can be accessed with good conversions and high enantioselectivities. Based on the experimental results and computational studies, we propose a mechanism that demonstrates the importance of both the α-helical structure and the presence of a hydrophobic groove of the homo-oligopeptide catalyst for reactivity and selectivity.

Facile epoxidation of α, β-unsaturated ketones with urea-2,2-dihydroperoxypropane as a new oxidant

Abstract: Various aromatic α, β-unsaturated ketones were successfully transformed into their corresponding epoxides using urea-2,2-dihydroperoxypropane as the oxygen source for the first time. The reactions were carried out under mild alkaline conditions at room temperature in high yields and short reaction times. Graphical Abstract: [Figure not available: see fulltext.]

Biomimetic epoxidation in aqueous media catalyzed by cyclic dipeptides

We have developed a practical epoxidation of electron-deficient enones in aqueous media using cyclic dipeptides as bioinspired green catalyst. Optimizing the reaction conditions in a triphasic system led to efficient conditions providing epoxides with good enantioselectivities. Depending on the catalyst substituent chirality, both enantiomers are obtained. The cyclic rigidity impacts significantly the enantioselectivity.
