Compounds of the formula I:
wherein:
A' and A" are independently the same or different group of the formula II:
wherein:
R' is H, CH3, C(CH3)2, -ORa, -N(Ra)2, -N(Ra)ORa or -DP
R''' is H or CH3; Ra is H, C1-C3 alkyl;
D is a bond, alkylene, -C(=O)-, -S(O)- or -S(O)2- ;
P is an optionally substituted, mono or bicyclic carbo- or heterocycle;
R" is H, any of the sidechains found in the natural amino acids, carboxacetamide, or a group (CH2)nDP;
M is a bond or -C(=O)N(R''')-;
Q is absent, a bond, -CH(OH)- or -CH2-;
or R" together with Q , M and R' define an optionally substituted 5 or 6 membered carbo- or heterocyclic ring which is optionally fused with a further 5 or 6 membered carbo- or heterocyclic ring;
with the proviso that R' is -ORa, -N(Ra)2, -N(Ra)ORa or -DP, if M is a bond and Q is absent; X is H, OH, OCH3;
Y is H, OH, OCH3, but X and Y are not both H;
Z' and Z" are independently -(CH2)mP where P is as defined above;
n and m are independently 0,1 or 2;
and pharmaceutically acceptable salts and prodrugs thereof have utility as aspartyl protease inhibitors of HIV. They can be prepared in a facile two step synthesis from novel 2,5-di-O-benzyl-L-mannaro-1,4:6,3-dilactone intermediates.
