Synthesis of unsymmetric cyclic urea diols, a novel class of HIV protease inhibitors

Unsymmetric cyclic urea diols of general structure 1 can be prepared either via an isourea derived from the symmetric diamine 2 or by the selective removal of a benzyl group from certain symmetric cyclic ureas 8, employing dissolving metal reduction.
