Silyl Nitronate Cycloadditions Catalyzed by Cu(II)-Bisoxazoline

不对称催化

手性异恶唑啉合成

Cu(OTf)2 and chiral BOX ligand-catalyzed 1,3-dipolar cycloadditions of triisopropylsilyl nitronates with α,β-unsaturated carboximides produced chiral isoxazolines in high yields, high enantioselectiv

Enantioselective Diels−Alder Reaction of Simple α,β-Unsaturated Ketones with a Cinchona Alkaloid Catalyst

不对称催化

有机合成方法

The simple α,β-unsaturated ketones and 2-pyrones are readily available and synthetically important dienophiles and dienes, respectively, for Diels−Alder reactions. However, both prove to be challengin
