The 1,6‐electrocyclization of 1‐(2‐pyridyl)‐2‐azabuta‐1,3‐dienes, obtained by RhII‐catalyzed reaction of pyridotriazoles with 2H‐azirines, affords stable non‐aromatic 4H‐pyrido[1,2‐a]pyrazines despite the fact that the reaction proceeds with irreversible dearomatization of the pyridine aromatic system.
通过Rh II催化的吡啶三唑与2 H叠氮基的反应获得的1-(2-吡啶基)-2-azabuta-1,3-二烯的1,6-电环化可提供稳定的非芳族4 H吡啶基[ 1,2- a ]吡嗪,尽管该反应会随着吡啶芳族体系的不可逆脱芳香化而进行。

The thermal decomposition of aryldiazoacetates and aryldiazoketones in the absence of a catalyst leads to synthetically useful transformations. The thermal reaction of aryldiazoacetates with alkenes generates cyclopropanes in 68-97% yield and with good diastereoselectivity (up to 19:1 dr) when the aryl substituent is electron-rich. The thermal reaction of aryldiazoketones with alkenes generated cyclobutanones in 71-94% yield and with good diastereocontrol (>= 9:1 dr).
