A method for producing unsymmetrical cyclic ureas through monoacylated diamine intermediates |
| abstract |
The solution relates to an improved preparation processnunsymmetrical cyclic ureas of formula VIanalso intermediates in the preparation of unsymmetrical cyclicnureas. In this process, the diamine of formula I-a is selectivelynmonoacylated to give unsymmetrical monoacylatedndiamine, which can be converted to an unsymmetrical intermediate.nThis unsymmetrical intermediate can be further alkylated,ncyclize and / or modify to form compounds that arenuseful as HTV protease inhibitors for the treatment of HIV infection.nThe invention makes available the preparation of a number of asymmetric seriesncyclic ureas. |
