Photolysis of I-(1-alkoxy-l-alkenyl)benzotriazoles gives moderate yields of 2-alkoxyindolenines, which can be hydrolysed to oxindoles. A side reaction leads to the formation of iminooxetanes. The formation of the 2-alkoxy-indolenines is quite insensitive to steric hindrance at the reacting centres.
