Syntheses of Sequence-Controlled Polymers via Consecutive Multicomponent Reactions

Multicomponent reactions have recently attracted a great deal of attention as they are considered as a powerful tool for constructing sequence-controlled polymers. Although new examples are constantly flourishing in the literature, the process that allows two or more consecutive multicomponent-reactions to react in a single operation for the syntheses of sequence-controlled polymers has not been developed until now. Here, we propose a new strategy combining multicomponent reaction of amine, thiol, and alkene conjugating and multicomponent polymerization of diyne, azide, and diamine coupling in one-pot for the synthesis of sequence-controlled polymer.
