• R.sub.2 and R'.sub.2 represent two hydrogen in the case where the bicyclooctane ring is unsaturated, or alternatively
• R.sub.2 or R'.sub.2, in the case where the cyclooctane ring is saturated, which are identical or different, represent hydrogen or halogen, hydroxy, linear or branched (C.sub.1 -C.sub.6) alkyl, linear or branched (C.sub.1 -C.sub.6) alkoxy, cyano, amino (unsubstituted or substituted by one or two linear or branched (C.sub.1 -C.sub.6) alkyl) or oxo,
• R.sub.3 represents any one of the following groups:
• --CO.sub.2 H (on the condition that in this case, R.sub.1 is different from halogen, linear (C.sub.1 -C.sub.6) alkyl or amino), ##STR38## in which:
• m represents 1, 2 or 3,
• X represents oxygen or sulfur or N-R (in which R is hydrogen or linear or branched (C.sub.1 -C.sub.6) alkyl),
• R.sub.5 or R.sub.6, which are identical or different, represent hydrogen, linear or branched (C.sub.1 -C.sub.6) alkyl, trifluoromethyl or ##STR39## forms (C.sub.3 -C.sub.6) cycloalkyl, n represents 0, 1 or 2,
