The diester of N‐methyl‐N‐(o‐carboxyphenylj‐alanine (I b)) gives by D IECKMANN reaction 1,3‐dimethyl‐3‐hydroxy‐oxindole (VIII), which is probably the product of a rearrangement of 1,2‐dimethyl‐2‐hydroxy‐oxindole (V), this latter being the product of autoxydation of the primary formed 1,2‐dimethyl‐indoxyle. VIII seems not to be in equilibrium with V.
