Abstract
The crystal structure analysis of ro-9-isopropyl-10,10-dimethyl-2,7-di aza-9-anthrol, C21H28N2O3, obtained from the condensation of 3-bromo-2 -ethoxypyridine with diisopropyl ketone enolate in the presence of the complex base NaNH2.(t)BuONa, shows the tricyclic nature of the compou nd and allows interpretation of the reaction mechanism. The structure and conformation of the two independent molecules present in the asymm etric unit are compared with molecular modelling results.
