A new method for substitution of allenoate using oxindoles as nucleophilic reagents has been developed in this study under phosphine catalysis, leading to 3-allenic or 3-dienoic oxindoles. Plausible reaction mechanisms have been proposed based on previous works.
A new method for substitution of allenoate using oxindoles as nucleophilic reagents has been disclosed in this paper upon phosphine catalysis under mild conditions to afford 3-allenic or 3-dienoic oxindoles in moderate to good yields depending on the substituent at the aromatic ring of oxindole. According to the previous works, the plausible reaction mechanisms have been proposed.
