di-addition of silylnitronates and nitrile oxides is a useful procedure for functionalizing butadiene leading to cyano and acyl derivatives. A novel route to 2,5-disubstituted furans is also established. The potential of the method in carbohydrate synthesis is pointed out. The route via 2-isoxazoline is shown to be a useful alternative to aldol-type reactions in organic synthesis. 15a has been studied by X-ray
甲硅烷基亚硝酸盐和腈氧化物的单和双加成是使丁二烯官能化生成氰基和酰基衍生物的有用方法。还建立了向2,5-二取代的呋喃的新途径。指出了该方法在碳水化合物合成中的潜力。已证明通过2-异恶唑啉的途径是有机合成中羟醛型反应的有用替代方法。已经通过X射线衍射研究了15a,并且显示为内消旋形式。
