The reaction of 3,4-dihydro-β-carboline 5a with the nitrile oxide generated from 4-fluoro-N-hydroxybenzenecarboximidoyl chloride (6) gave novel adduct 7a that on standing at 26 °C in CDCl3 was isomerized to species 8. As an extension, the reaction of the dihydro-β-carbolines substituted on C(1) (5b-e) afforded the analogous adducts (7b-e). In case of using two equivalents of reagent 6, the corresponding 1,2,4-triazole-2-oxide (10b-e) was also formed beside the adduct (7b-e).
3,4-二氢-β-咔啉5a与由4-氟-N-羟基苯甲酰亚胺氯生成的氰酸酯反应,得到了新的加合物7a,该加合物在CDCl3中26°C下静置时异构化为物种8。进一步扩展,C(1)位取代的二氢-β-咔啉(5b-e)反应生成了类似的加合物(7b-e)。当使用两当量的试剂6时,除了加合物(7b-e)外,还生成了相应的1,2,4-三唑-2-氧化物(10b-e)。
