8-tetradehydromorphinan-6-carbonitriles. Addition of nucleophiles such as Li diisopropylamide or Grignardreagents to the acrylonitrile substructure yielded ring-opened 5,6-didehydro products. Seven products were characterized by X-raycrystalstructure analysis and revealed insight into the mechanistic diversity of the van Leusen reaction.
