In the course of studies directed toward 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.
在针对双脱氧 lomaiviticinone 合成的研究过程中,制备了 3-(硝基甲基) 环己烯酮2a (X = H) 和2b (X = I)。相应的烯醇化物与萘甲素 ( 1 )反应并出人意料地分别得到 1,2-氧氮杂3和异恶唑4。提出了其形成的基本原理。
