REACTION OF NITRILIMINES WITH CYCLOALKANONE OXIMES. II.[1] SYNTHESIS OF SUBSTITUTED HETEROCYCLIC SPIRO COMPOUNDS

ABSTRACT

Hydrazonoyl halides (1a–e) react with cycloalkanone oximes (2–6) to give substituted heterocyclic spiro compounds (8–11a–e). Reaction of triazaspiro[4.5]dec-2-ene (9b) with acetic anhydride gave the ring transformation product triazole (17b) instead of the N-acetyl derivative (16b).
