Abstract

The reaction sequences that followed the action of orthoesters upon ureas were dependent upon the nature and position of substituents on the urea, the particular orthoester and the reaction conditions. Products obtained were ethoxymethylene, diethoxymethyl, and a- ethoxyethylidineureas, mono-and dicarbamylformamidines, urethans, 2-benzylidinecarbazic esters, 1, 3-diarylformamidines, N-formylureas, aryltriazolones and 2-amino-1, 3, 4- ...
