A solid phase synthesis has been developed leading up to unsymmetrical HIV-1 protease inhibitors that are not readily available by conventional solution phase chemistry (18a-g). To prepare these compounds the hydroxyl group of (1S,2R)-(-)-cis-1-phthalimido-2-indanol (3) was coupled to a Merrifield resin via a dihydropyrane linker. Cleavage of the phthalimido protecting group and reaction of the liberated amine with the bis-activated symmetrical diacid 15 resulted in the resin bound amide 16. Coupling of 16 with amino acids and amines followed by hydrolysis produced the desired unsymmetrical products 18a-g from which potent HIV-1 protease inhibitors were identified, e.g., 18e (k(i) = 0.1 nM), 18a (k(i) = 0.2 nM) and 18c (k(i) = 2 nM).
