N-Allylynamides with various functional groups and different substitution patterns can be converted into 3-aza-bicyclo[3.1.0]hexan-2-one derivatives in moderate to high yield using IMesAuCl/AgBF4 as the catalyst and pyridine N-oxide as the oxidant. A noncarbene mediated approach is proposed as the mechanism.
使用IMesAuCl / AgBF 4作为催化剂,吡啶N-氧化物作为溶剂,可以将具有各种官能团和不同取代方式的N-烯丙基炔酰胺以中等至高产率转化为3-氮杂双环[3.1.0]己-2-酮衍生物。氧化剂。提出了非卡宾介导的方法作为机理。
