Reissert epoxides: Novel oxidation products of quinoline reissert compounds
摘要:
Treatment of quinoline Reissert compounds with m-chloroperoxybenzoic acid gave epoxides which are remarkably stable in crystalline state, but reactive in solution versus nucleophiles. They represent useful intermediates to regioselectively functionalized quinolines.
The CN shuffle: The described intramolecular alkenyl‐ and acylcyanation reaction of activated alkenes proceed by cleavage of a CN bond. This protocol provides access to functionalized acyclic nitriles with quaternary carbon centers under neutral and mild reaction conditions, demonstrates broad scope, and good functional‐group compatibility and versatility.
