Popis: The scope of acid-mediated cyclative additions of electrophiles to tryptophan-derived α-amino nitriles for the synthesis of 10 b -substituted-1,2,4,5,10 b ,10 c -hexahydropyrrolo[1′,2′,3′:1,9 a ,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 10 b -bromo-derivatives, by bromination with NBS, 10 b -allyl-derivatives, by bromo-allyl exchange, and 10 b -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 μM cytotoxicities in human cancer cell lines and at 10 μg/mL inhibited more than 50% EGFR or HIF-1α.
