Expedient Iodocyclization Approach Toward Polysubstituted 3H‐Benzo[e]indoles

et al. 2015

A facile and expedient iodocyclization of 4-(2-prop-1-ynylphenyl)-1H-pyrroles towards the synthesis of polysubstituted 3H-benzo[e]indoles is reported. The transformation was optimized and the best results were obtained by using iodine (1.2 equiv,) in dichloromethane, and potassium carbonate as base. The starting 1,2,3,4-tetrasubstituted pyrroles were efficiently obtained by means of a nickel(II) chloride-promoted four-component (nitromethane, amine, 2-alkynylbenzaldehyde and ethyl acetoacetate) reaction. Further functionalization of the resulting 5-iodoheterocycles was also explored.Fil: Martins, Guilherme M.. Universidade Federal de Santa Maria. Departamento de Qu ímica; BrasilFil: Zeni, Gilson.
