3,3-Dialkyl- or 3,3-alkylene-indolines which are unsubstituted at the 1- and 2-positions and which are substituted at the 4- or 6-position by an optionally etherified hydroxy group or substituted at the 5- or 7-position by an etherified hydroxy group, as well as their physiologically-hydrolyzable and -acceptable esters. The said indolines and esters as well as their pharmaceutically acceptable acid addition salts possess analgesic activity.
