  日期：——

  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
