10c-hexahydropyrrolo[1',2',3':1,9a,9]imidazo[1,2-a]in doles analogues of indole alkaloids has been studied. The results demonstrate the high potential of the methodology for the synthesis of 10b-bromo-derivatives, by bromination with NBS, 10b-allyl-derivatives, by bromo-allyl exchange, and 10b-prenyl-derivatives, by reaction with prenyl bromide in the presence of Mg(NO(3))(2).6H(2)0. Some of the new pyrroloimidazoindole
色氨酸衍生的α-氨基腈的亲和酸的酸介导环加成反应的范围,用于合成10b-取代的1,2,4,5,10b,10c-六氢吡咯[1',2',3':1吲哚生物碱的doles类似物中的,9a,9]咪唑并[1,2-a]已被研究。结果表明,通过与NBS溴化,10b-烯丙基衍生物,通过溴-烯丙基交换和10b-异戊烯基衍生物(通过与异戊烯基溴化物反应)合成10b-溴衍生物的方法学具有很高的潜力。 Mg(NO(3))(2).6H(2)0的存在。一些新的吡咯并咪唑并吲哚衍生物在人癌细胞系中表现出中等的microM细胞毒性,以10 microg / mL的浓度抑制50%以上的EGFR或HIF-1alpha。
