The synthesis of periodic copolymers with a regularly recurring sequence in one direction along the polymeric backbone is presented, applying a step‐growth polymerization of heterofunctionalized precision macromonomers derived from solid phase synthesis (SPS) via photoinduced thiol‐ene coupling (TEC). Heterofunctional macromonomers with monomer sequence‐control of the AB type present a terminal alkene...
Alkylation of N‐vinylpyrrolidone using lithium diisopropylamide and bis(2‐bromoethyl) ether was carried out to obtain 3‐(2‐(2‐bromoethoxy)ethyl)‐1‐vinyl‐2‐pyrrolidone (2). The derivative 2 represents a versatile starting molecule for further modification via nucleophilic displacement yielding, for example, the bicyclic 2‐vinyl‐8‐oxa‐2‐azaspiro[4.5]decan‐1‐one (4) or the ammonium salt 3‐diethoxy‐N,...
