DOI: 10.1016/j.molstruc.2020.128308
Abstract: Abstract A number of bis-indolyl imine helical structures has successfully been synthesized employing Schiff base reaction conditions starting from 4,6-dimethoxy-2,3-diphenylindole with different o-phenyl diamines as π-spacer bridged. The structures of targeted compounds were identified by…
