Indoline compounds represented by the general formula: ##STR1## wherein R.sup.1 represents the group ##STR2## R.sup.2 represents a phenyl group which may be substituted or an aromatic heterocyclic group, and R.sup.3 represents hydrogen, a halogen, or a lower alkyl group, hydroxyl group, lower alkoxy group, carbamoyl group or lower alkoxycarbonyl group, and physiologically acceptable salts thereof, and their solvates, as well as 5-HT.sub.3 receptor antagonists containing them as effective components. The indoline compounds of the invention have stronger antagonism against intestinal 5-HT.sub.3 receptors than known 5-HT.sub.3 receptor antagonists and also have excellent sustained action, making them useful as prophylactic or therapeutic agents against vomiting or irritancy induced by chemotherapy or radiation, irritable bowel syndrome, diarrhea, and the like.

This invention concerns a method for the production of a 3-arylindoline compound represented by the general formula
(wherein R1 represents an optionally substituted phenyl group or an aromatic heterocyclic group and R2 represents a hydrogen atom, a halogen atom, a lower alkyl group, a hydroxy group, a lower alkoxy group, a carbamoyl group, or a lower alkoxycarbonyl group) which is used for the production of a 1-acyl-3-arylindoline compound represented by the general formula
(wherein R1 and R2 have the same meanings as defined above and R3 represents the following group)
which is the 5-HT3 receptor antagonist, based on the fact that a 1-acyl-3-arylindole compound obtained by having a removable electron withdrawing group linked thereto by acylating the 1 position of a 3-arylindole compound with such an organic acid as carboxylic acid or sulfonic acid easily undergoes a catalytic reduction under neutral or acidic conditions and gives rise to a 1-acyl-3-arylindoline compound and that an optically active 1-acyl-3-arylindole compound obtained by the acylation with an organic acid such as optically active carboxylic acid or sulfonic acid produces an optically active 1-acyl-3-arylindoline compound with high selectivity by the reaction of a catalytic reduction.
