2-Ethoxy-3,4-dihydro-2H-pyran-6-carbonitriles are obtained in high yield by stereospecific endo-mode cyclo-additions of α,β-unsaturated acyl cyanides and ethyl vinyl ether at room temperature. The nitrile group is converted to some other functionalities.
在室温下,通过α,β-不饱和酰基氰化物和乙基乙烯基醚的立体定向内模环加成,可以高收率地获得2-乙氧基-3,4-二氢-2 H-吡喃-6-腈。腈基转化为一些其他官能团。
