Three-step cascade: Oxazepine derivatives were efficiently prepared from O-propargylic oximes and dipolarophiles through copper-catalyzed cascade reactions which proceed through a 2,3-rearrangement, [3+2] cycloaddition, and subsequent 1,3-oxygen rearrangement. The process involves the cleavage of C- and N-O bonds.
通过铜催化的级联反应,从 O-炔丙基肟和偶极子高效制备了噁嗪衍生物,该反应经过 2,3-重排、[3+2]环加成和随后的 1,3-氧重排。该过程涉及 C-和 N-O 键的断裂。
