    摘要: The compounds of formula I ##STR1## wherein Ar represents biaryl, carbocyclic or heterocyclic aryl, are prepared, as substantially pure enantiomers, by(a) condensing a compound of the formula ##STR2## as a substantially pure enantiomer, wherein Ar has meaning as defined above and R.sub.6 is on O-protecting group with a lower alkyl ester of formic acid;(b) then condensing the compound so obtained with a compound of the formula ##STR3## wherein R.sub.8 is hydrogen or COOR.sub.3 and R.sub.3 is lower alkyl; (c) then cyclizing the compound so obtained to a compound of the formula ##STR4## as a substantially pure enantiomer; (d) and then condensing the compound so obtained(1) with a carbocyclic aroyl isothiocyanate and treatment of the product so obtained with an alkyl halide followed by anhydrous ammonia; or(2) with cyanamide in acid, optionally followed by treatment with a base.
