Chemistry is traditionally divided into organic and inorganic chemistry. Formula: C9H7NO, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 1532-72-5
A formal [3+2] cycloaddition of N-aryl alpha-amino acids with isoquinoline N-oxides via visible light-driven photoredox catalysis is reported. Under transition metal-free conditions using a dicyanopyrazine-derived chromophore (DPZ) as the photoredox catalyst, the transformation was efficient and led to a series of important diazabicyclo[3.2.1]octane-based N-heterocyclic compounds. This work demonstrates the synthetic utility of N-aryl alpha-amino acids as 1,2-synthons and provides a new strategy for the dearomatization of isoquinolines.
