[3+2] Cycloaddition of alkynes to resin bound nitrile oxides gives after cleavage of 3,4,5 trisubstituted isoxazoles in acceptable yields and fair to good purity, depending on the alkyne substituents. The reaction has been automated on the ACT 496 synthesiser.
[3 + 2]炔烃与树脂键合的腈氧化物的环加成反应在裂解3,4,5三取代的异恶唑后,可以得到可接受的收率,并且纯度取决于纯度,取决于炔烃的取代基。该反应已在ACT 496合成仪上自动进行。
