with hydroxylamine hydrochloride affords three compounds: the oxime of 2‐benzylidenecyclohexanone (2), 3‐phenyl‐7‐benzylidene‐3,3a,4,5,6,7‐hexahydro‐2,1‐benzisoxazole (3) and 3‐phenyl‐3,3a,4,5,6,7‐hexahydro‐2,1‐benzisoxazole‐7‐spiro‐2′‐(3′‐phenylaziridine) (4). Their structures were deduced by 2D NMR analysis. Single‐crystal x‐ray diffraction was used to confirm the structure and stereochemistry of
二苄基环己酮与盐酸羟胺反应得到三种化合物:2-亚苄基环己酮肟 (2)、3-苯基-7-苄基-3,3a,4,5,6,7-六氢-2,1-苯并异恶唑 (3) ) 和 3-苯基-3,3a,4,5,6,7-六氢-2,1-苯并异恶唑-7-螺-2'-(3'-苯基氮丙啶) (4)。它们的结构是通过 2D NMR 分析推导出来的。单晶 X 射线衍射用于确认 4 的结构和立体化学。提出了该反应的可能机制。
