Hydrocarbazole derivatives bearing a quaternary stereogenic center at C4a were synthesized by means of intramolecular oxidative dearomatization of diarylamines using hypervalent iodine in moderate to good yields. The hydrocarbazole bearing a cyclohexadienone moiety was further converted into the tetracyclic skeletons of Aspidosperma and akuammiline-type alkaloids via regioselective aza-Michael reaction at C4 and at C9a, respectively.Peptide-functionalized surfaces, composed of optimized l-peptides, show a high resistance towa
