Abstract
PURPOSE: Spiroamine derivatives of formula I (R1, R2, R3 are H, halogen, lower alkyl, lower alkoxy, benzyloxy, OH; X is O, CO, CHOH, -CH=CH-, single bond; A is lower alkylene, W is H2, O; R4 is H, lower alkyl, substd. or unsubstd. phenyl; R5 is H, or together with R4 forms lower alkylene) and their salts, e.g. 1'-(2-phenoxyethyl)-1-methyl-2-oxoindoline-3-spiro-4'-piperidine.
