and permethylated β-cyclodextrin (TRIMEB) and photolyzed. Because of supramolecularphotochirogenesis the generated carbenes afford intramolecular C–H insertion products not as a racemate but one enantiomer is slightly favored. With 1a@(6-Cy)2 the ee of product 7a is doubled. To the best of our knowledge for the first time for carbene reactions, products are imprinted, though modestly, with handedness
