Polymers with rigid three-dimensional architectures have attracted significant attention due to their high rigidity and intrinsic microporosity. Here, we report the synthesis of a new class stepladder polymers featuring unique spirodihydroquinoline skeletons. Under catalysis half-sandwich scandium catalyst, quinoline compounds bearing both an aryl substituent (e.g., phenyl or naphthyl) alkynyl group C≡CSiMe3) selectively undergo dearomative polyspiroannulation between skeleton alkyne unit via ortho-C–H activation group. This reaction efficiently yields comprising quaternary carbon stereocenter unprotected N–H Treatment N–H-containing alkyl lithium reagent followed by methyl iodide leads quantitative formation corresponding N-methylated polymers, which exhibit enhanced thermal stability porosity compared counterparts.
