A new procedure for the synthesis of 2-azabicyclo[3.3.1]nonanes by intramolecular carboradical cyclization of 4-(trichloroacetamido)cyclohexenes substituted with an electron withdrawing substituent (ester or nitrile) is described. The procedure allows the preparation of synthetically interesting azabicyclos 14 and 15 in nearly 70% yield.
描述了一种通过分子内碳环化被吸电子取代基(酯或腈)取代的4-(三氯乙酰胺基)环己烷进行2-氮杂双环[3.3.1]壬烷合成的新方法。该方法允许以接近70%的产率制备合成上令人感兴趣的氮杂双环14和15。
