Abstract
A method for modifying nopinane-annelated 4,5-diazafluorene by introducing butyl groups and an additional amide group is proposed. Stereoselectivity of the formation of a single isomer by the substitution of a benzyl methylene group of pinane system is demonstrated. The structure of the new substances is established using a set of physicochemical methods. The synthesised substances can be promising tridentate ligands and extractants for d- and f-elements.
