ABSTRACT:
The invention provides new derivatives of the formula: ##STR1## in which either (a) Y=COOH or a radical of the formula (II), in which R.sub.2 =alkyl or benzyl, A=a sulphur atom, m=1, n=0, R=pyridin-3-yl and R.sub.1 =H, or (b) Y=CN, COOH or a radical of the formula ##STR2## defined as above, A=S, O or CH.sub.2, m=1 or 2 and n=0, 1 or 2, (m+n) being 1, 2 or 3, R=H, alkyl or phenyl (optionally substituted by halogen, alkyl, alkoxy or CF.sub.3) and R.sub.1 =a radical of the formula ##STR3## in which p=0 or 1, the alkyl radicals and alkyl portions being straight-chain or branched-chain and containing 1 to 4 carbon atoms each. Processes for the production of these compounds are described. They are useful as intermediates for the preparation of new medicaments.
