Catalytic alkylation of cycloalkaneindoles and tetrahydro-γ-carboline with 9-oxiranylmethylcarbazole

Abstract

Catalytic alkylation of substituted indoles such as cycloalkaneindoles and tetrahydro-γ-carboline using 9-oxiranylmethylcarbazole leads to the formation of 1-(carbazol-9-yl)-3-{dihydrocycloalkane[b]indol-4(1H)-yl}propan-2-ols and 1-(carbazol-9-yl)-3-{2,8-dimethyl-3,4-dihydro-1H-pyrido[4,3-b]indol-5(2H)-yl}propan-2-ol, conjugates containing 2-hydroxypropylene spacer.
