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