Baylis–Hillman adduct with nitrile oxides is described. The reaction has shown to proceed with moderate diastereoselectivity, favoring the syn isomer of the resulting 3,5-substituted isoxazolines. The stereochemistry of the products has been assigned using 1H NMR studies. The structure of one of the diastereomers has been determined by single-crystal X-ray crystallographic analysis.
描述了可溶性聚合物负载的Baylis-Hillman加合物与腈氧化物的非对映选择性环加成反应。将反应已经显示出中度非对映选择性进行,有利于顺式所得3,5-取代的异恶唑啉的异构体。产品的立体化学已通过1 H NMR研究确定。非对映异构体之一的结构已经通过单晶X射线晶体学分析确定。
