text: An M1R with a protected-amine group at the ω terminal () as a linear polymer was subjected to N protection with trichloroethyl chloroformate at the α terminal and successive N′ deprotection with an arenethiol at the ω terminal to convert it to cyclic polymer (), which was then treated with-nitrobenzenesulfonyl chloride and Zn/AcOH and reverted to the linear polymer.
