This ivention relates to novel perhydroisoindole derivatives having formula (I), ##STR1## wherein the symbols R, which are the same or different, are phenyl radicals optionally 2- or 3-substituted by a halogen atom or a methyl radical, R' is a phenyl radical optionally 2-substituted by a C.sub.1-2 alkylk or alkyloxy radical, R" is a fluorine atom or a hydroxy radical, and R'" is a hydrogen atom, or else R' and R'" are hydroxy radicals, or R" and R'" together form a bond, and R.sup.o is a hydrogen atom or a protective radical; salts thereof whereever applicable; and preparation thereof. These products are synthetic intermediates for the preparation of derivatives having P substance antagonist activity.
