中文摘要 | convenient and efficient synthesis of spiro-fused pyrazolin-5-one n-oxides starting from readily available 1-carbamoyl-1-oximylcycloalkanes is developed. this general protocol features a novel and facile way for access to the five-membered azaheterocycles by formation of a new n-n single bond. the key cyclization step utilizes the formation of an n-oxonitrenium intermediate, mediated by the hypervalent iodine reagent pifa, and its subsequent intramolecular trapping by the amide moiety under rather mild experimental conditions. |
