enantioselectively to 2(1H)-quinolones upon irradiation (λ = 366 nm) in the presence of a chiral complexing agent. A two-point hydrogenbond between the quinolone and the template is responsible for stereocontrol in the photocycloaddition reaction. The reaction leads to the formation of products with a chiral bicyclo[2.1.1]hexane skeleton in high enantiomeric excess (91–99% ee). The chiraltemplate can be almost

Abstract An efficient synthesis of novel alkyl 2-oxo-1,2-dihydroquinoline-4-carboxylates (3a-3d) was developed, starting from 2-oxo-quinoline carboxylic acid 1a which successively undergoes esterification and alkylation reactions. The structures of all the obtained compounds were investigated and characterized by using 1H NMR and 13C NMRspectroscopic measurements. The molecular and crystal structures
