Treatment of α-dithiolactone 6 with ethoxycarbonylformonitrile oxide 7 resulted in the formation of 1,2-dithietan-3-one 4. Compound 4a was oxidized with m-CPBA to give 4,4-di-tert-butyl-1,2-dithietan-3-one 1-oxide 5a. The reaction of 4a with triphenylphosphine afforded the corresponding α-thiolactone 10.
用乙氧基羰基甲腈氧化物7处理α-二硫代内酯6导致形成1,2-二硫代坦-3-酮4。化合物4a中用氧化米-CPBA,得到4,4-二-叔-丁基-1,2-二硫环丁烷-3-酮-1-氧化物5a中。4a与三苯基膦反应,得到相应的α-硫代内酯10。
