| titleOfInvention | Preparation of asymmetric cyclic ureas through a monoacylated diamine intermediate |
| abstract | The present invention concerns an improved process for the preparation of asymmetric cyclic ureas as well as intermediates in the preparation of asymmetric cyclic ureas of formula (VI): wherein: R7 is selected from the following: C¿1?-C8 alkyl substituted with 0-3 R?11; C¿2-C8 alkenyl substituted with 0-3 R11; C2-C8 alkynyl substituted with 0-3 R11; and a C¿3?-C14 carbocyclic ring system substituted with 0-3 R?11; R10 is C1-C10¿ alkyl, benzyl, naphthylmethyl, 3,4-methylenedioxybenzyl, or C¿1?-C4 alkyl substituted with phenyl wherein said phenyl is substituted with 0-3 R?10a¿; G taken together along with the oxygen atoms to which G is attached forms a group selected from: -O-C(-CH¿2?CH2CH2CH2CH2-)-O-, -O-C(CH2CH3)2-O-, -O-C(CH3)(CH2CH3)-O-, -O-C(CH2CH2CH2CH3)2-O-, -O-C(CH3)(CH2CH(CH3)CH3)-O-, -O-CH(phenyl)-O-, OCH2O-, -OC(CH3)2O- and -OC(OCH3)(CH2CH2CH3)O-. In the process, a diamine of formula (I-a) is selectively monoacylated to give an asymmetric monoacylated diamine which can be converted into asymmetric intermediates. The asymmetric intermediates can be further alkylated, cyclized, and/or modified to give compounds which are useful as HIV protease inhibitors for the treatment of HIV infection. The invention allows for scalable preparation of a wide variety of asymmetrical cyclic ureas. |
