Abstract
Abstract Allylaminoesters of the formula (I): ##STR1## in which: R 1 is H or low-molecular-weight alkyl, R 2 is low-molecular-weight alkyl, cycloalkyl, or low-molecular-weight phenylcycloalkyl, pyridyl or phenyl, low-molecular-weight phenylalkyl, low-molecular-weight diphenylalkyl, low-molecular-weight phenylalkenyl, in which the phenyl cycle may be mono-, di- or trisubstituted by chlorine atoms, low-molecular-weight alkyl radicals, low-molecular-weight alkoxy, or trifluoromethyl, acetamide or acetyloxy radicals, their racemic forms, their (S) enantiomers and their addition salts. Also, antiallergic drugs containing the same.
