Herein, we report the synthesis of N‐heterocycles by borane‐catalyzed dehydrogenative cyclization of 2‐cyclopropyl‐N,N‐dimethylanilines. Borane‐mediated cyclopropane ring‐opening and borane‐mediated hydride abstraction from an N‐methyl group are the key steps. The substituent at the cyclopropyl unit was found to greatly influence the reaction pathway and thus determined the major reaction product...
A novel molecularly imprinted composite nanofiber was prepared by a simple electrospinning technique, in which polyvinylbutyral (PVB) was chosen as matrix, β‐cyclodextrin (β‐CD) was used as a functional monomer and naringin (NG) as template molecules. After cross‐linked by hexamethylene diisocyanate (HMDI), the composite nanofiber exhibited a high specific binding capacity. The morphological structure...
