CuI-mediated atom transfer radical cyclization of amino-tethered dichloromalonamides and electron-rich, electron-poor, and nonactivated double bonds is a useful methodology for the synthesis of 2-azabicyclo[3.3.1]nonanes. A study of the reaction conditions and the scope of the process is reported. Cyclopropane ring formation was observed from the resulting 1,3-dichlorides in some morphan substrates using
CuI 介导的原子转移自由基环化氨基连接的二氯丙二酰胺和富电子、缺电子和未活化的双键是合成 2-氮杂双环 [3.3.1] 壬烷的有用方法。报告了对反应条件和过程范围的研究。在一些使用 CuI、Pd 或 Zn 的吗啡底物中,从所得的 1,3-二氯化物观察到环丙烷环的形成。
