Asymmetric synthesis of chiral spiro bis(isoxazoline) and spiro (isoxazole–isoxazoline) ligands
TL;DR: Asymmetric synthesis of chiral ligands, bis(isoxazoline) on a spiro[4.4]nonane scaffold and isoxazole-isoxozoline on a polygonal spiro [4.5]decane scaffolding, has been achieved by utilizing an enantiomerically pure alcohol as the starting material.
Journal ArticleDOI
One-Pot Preparation of ChiralDinuclear Vanadium(V) Complex
TL;DR: The dinuclear vanadium(V) complex exhibited high catalytic activity for oxidative coupling of 2-naphthol derivatives and coupling of 9-phenanthrol gave (S)-10,10'-dihydroxy-9,9'-biphenanthryl in quantitative yield with 93% ee.
Journal ArticleDOI
Synthesis of spiro bis(1,2,3-triazolium) salts as chiral ionic liquids
TL;DR: In this paper, a chiral spiro ionic liquid based on 1,2,3-triazolium salts was synthesized via an intramolecular double Huisgen reaction.
Journal ArticleDOI
Synthesis of novel chiral spiro bis(pyrazole) ligands
TL;DR: The first synthesis of spiro bis(pyrazole) ligands, 2.2',4,4'-tetrahydro-6,6'-spirobi[5H-cycopentapyrazole] (la) and 2,2'-dibenzyl-2,2', 4,4-tetrahedro -6, 6'-SPIRObi[1] (1b) was achieved.
Journal ArticleDOI
Novel heterobimetallic asymmetric catalysis directing toward enzymatic function
TL;DR: In this article, a unique feature of multifunctional asymmetric catalysts is described, where catalytic asymmetric Michael reaction of cyclic enones with Horner-Wadsworth-Emmons reagents proceeds efficiently by use of an aluminum-lithium-BINOL complex that is activated by an addition of alkali metal reagent.
