treatment with tri-ethylamine leads to the formation of α-nitrosoolefins via α-nitrosochloride, which can react in situ intermol-ecularly with olefinic compounds to produce 5,6-dihydro-4H-1,2-oxazine derivatives in good yield.
含α-亚甲基的酮肟与氯胺-T反应,然后用三乙胺处理,可通过α-亚硝基氯化物形成α-亚硝基烯烃,后者可与烯烃化合物在分子间原位反应生成5,6-二氢-4 H -1,2-恶嗪衍生物的收率高。
