| abstract | The compounds of formula I (R1 = C1 to C6 alkyl, R3 = H) are prepared from the compounds of formula II by reaction with a corresponding Grignard compound R1MgX followed by a hydrolysis and a dehydrating cyclisation. Various substitutents R3 (ether and ester functional group) can then be introduced. The compounds of formula II are obtained by condensation of an ester of formula IV with a resorcinol of formula VI. The compounds of formula I and their derivatives of the hydroxyl function group in position 10 display an activity on the central nervous sytem and are useful as anxiolytic, tranquillising and analgesic agents. <IMAGE> <IMAGE> <IMAGE> <IMAGE> |
