A reaction of N-(4-formylphenyl)carbamates (1) with ethanolamine leads to a pseudomeric system of N-(2-hydroxyethyl)-4'-alkoxycarbaminobenzylideneimines (3), and undetectable (TLC, NMR) oxazolidines-1,3 (4).A subsequent reaction of the system with isocyanates results in exclusively urea derivatives of oxazolidine (5 and 6).This fact univocally confirms the tautomeric equilibrium of 34 system.All compounds obtained (3,5,6,8,9) were subjected to biological tests in order to elucidate their activity.
