Abstract: The scope of acid-mediated cyclative additions of electrophiles to tryptophan-derived alpha-amino nitriles for the synthesis of 10b-substituted-1,2,4,5,10b,10c-hexahydropyrrolo[1',2',3':1,9a,9]imidazo[1,2-a]indoles 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 derivatives displayed moderate microM cytotoxicities in human cancer cell lines and at 10 microg/mL inhibited more than 50% EGFR or HIF-1alpha.
