In the course of studiesdirectedtoward the synthesis of dideoxy lomaiviticinone, 3-(nitromethyl)cyclohexenones 2a (X = H) and 2b (X = I) were prepared. The corresponding enolates were reacted with naphthazarin (1) and unexpectedly afforded 1,2-oxazepine 3 and isoxazole 4, respectively. Rationale for their formation is proposed.
