The 5-exo-trig radical cyclization of an aryl halide onto a tethered vinyl chloride produces the 3-chloromethyl dihydroindole precursors for CC-1065 and duocarmycin analogs with chlorine installed as a suitable leaving group for subsequent cyclopropane spirocyclization. The generality of this approach was examined in the context of six CC-1065 and duocarmycin analogs previously synthesized in this
芳基卤化物在束缚的氯乙烯上的5- exo - trig自由基环化反应生成CC-1065和Duocarmycin类似物的3-氯甲基二氢吲哚前体,并安装了氯作为随后的环丙烷螺环化反应的合适离去基团。该方法的普遍性已在该实验室中先前合成的六种CC-1065和杜卡霉素类似物的背景下进行了研究。
