摘要:
Disclosed is a process for preparing a macrocyclic compound of the formula (I) wherein a hydroxyl-substituted macrocyclic compound of formula (3) is reacted with a sulfonyl-substituted compound of formula QUIN: The compounds of formula (I) are potent active agents for the treatment of hepatitis C virus (HCV) infection.
摘要:
Disclosed are highly convergent processes for preparing compounds of formula (I), which compounds are potent active agents for the treatment of hepatitis C virus (HCV) infection: The disclosed processes use SNAr-type coupling reactions between peptidic compounds having a hydroxyproline moiety of the following formula: and halogenated or sulfonated bromoquinoline compounds.
摘要:
An improved process for making chiral, .alpha.-methylated, .alpha.-substituted amino acids of the formula I ##STR1## wherein Y is a hydrogen atom and R.sub.2 is the residue of a natural or unnatural amino acid, in which process an oxazolidinone of the formula II ##STR2## is formed by reacting a protected amino acid of the formula IA ##STR3## wherein Y is a protecting group, with an aldehyde of the formula RCHO, or an equivalent thereof, in the presence of a chlorinating agent and a Lewis acid.The group R.sub.2 is introduced into the oxazolidinone intermediate of formula II in a conventional manner, and subsequent hydrolysis and deprotection, both carried out in a conventional manner, yield the chiral, .alpha.-methylated, .alpha.-substituted amino acid.
摘要:
"There are disclosed compounds of the formula I, II or III ##STR1## wherein A and D are carbon or nitrogen and B is oxygen, sulfur or nitrogen which are useful in the prevention or treatment of HIV infection."
摘要:
Novel compounds for the treatment of HIV-1 infection. These are 2-heteroary-5,11-dihydro-6H-dipyrido�3,2-b:2',3'-e!�1,4!diazepines of the formula ##STR1## wherein Z is oxygen, sulfur, .dbd.NCN or .dbd.NOR.sup.10 and Ar is a group of the formula I, II, III, IV or V ##STR2##
