PRIORITY: US 1995-448795 24 May 1995. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 1, 34 A class of compds. for the treatment of viral infections is disclosed, specifically I [R, R2 = H, halo, alkyl, (un)substituted NH2; R1 = H, halo, alkoxy, alkyl; R3 = H, alkyl, alkylaminoalkyl, aralkyl, heterocyclylalkyl; R4 = H, alkyl, cycloalkyl, aryl, aralkyl, heterocyclyl, (un)substituted carboxyalkyl, carbamoylalkyl, hydroxyalkyl, or aminoalkyl] and their pharmaceutically acceptable salts. I are viral protease inhibitors, useful esp. for treatment of infection by CMV, HSV-1, HSV-2, etc. For example, L-alanine tert-Bu ester HCl was coupled with 2-amino-6-methylbenzoic acid using CDI in pyridine, followed by cyclization using EDC and Et3N in CH2Cl2, to give title compd. II. Assays of I for inhibition of HCMV protease, chymotrypsin, and human leukocyte elastase are given, as well as cell culture assay results for antiviral activity and cytotoxicity against HCMV in human fibroblasts. Synthesis of approx. 220 compds. I is described, with biol. data for many examples. .

DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 1 Processes for sepn. of enantiomers of clopidogrel, and converting one enantiomer of clopidogrel to another enantiomer of clopidogrel are provided. The enantiomers are sepd. by crystg. the (S) enantiomer as camphor sulfonate salt from a hydrocarbon, or a mixt.Several substances with their cas registry numbers 30433-91-1 and 90055-48-4 may be metioned in this study. of a hydrocarbon and a co-solvent, preferably DMF:toluene. The (R) enantiomer is then racemized and recycled by reaction with a catalytic amt. of a base, preferably with tert-butoxide. Thus, a soln. of racemic clopidogrel in toluene was added to a soln. of (-)-(R)-camphorsulfonic acid (CSA/Rac clopidogrel = 0.6/1 mol/mol) in DMF at 30°, seeded with (+)-(S)-a-(2-chlorophenyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridin-5-ylace tic acid Me ester-(-) CSA salt (I), and then cooled to 15° to affect crystn. of the product. The product was filtered, washed with toluene, then dried under vacuum at ￡35°. After one crystn. of the salt I from acetone, it was added to EtOAc/H2O and treated with NaOH and Na2CO3. The org. phase was sepd., washed with water, decolorized with charcoal, filtered, concd., dissolved in acetone, treated with H2SO4, seeded with clopidogrel polymorph seed, aged, filtered, and dried under vacuum at <25° to give chlorogrel bisulfate. .
