Liu, Zhaosheng published the artcilePhotoredox Cyclization of N-Arylacrylamides for Synthesis of Dihydroquinolinones, COA of Formula: C8H11NO, the main research area is arylacrylamide cyanoarene photocatalyst photoredox cyclization; dihydroquinolinone regioselective preparation.
Metal- and additive-free photoredox cyclization of N-arylacrylamides was herein reported that provided a concise access to the formation of dihydroquinolinones. In this protocol, sustainable visible light was used as the energy source, and the organic light-emitting mol. 4CzIPN served as the efficient photocatalyst. This reaction system features exclusive 6-endo-trig cyclization selectivity with a generally good yield of a range of functionalized dihydroquinolinones and dihydrobenzoquinolinones. Mechanistical studies reveal the feasibility of both 1,3-H shift and intersystem crossing of the diradical intermediate.
Organic Letters published new progress about Photocyclization (regioselective). 5961-59-1 belongs to class isoquinoline, name is 4-Methoxy-N-methylaniline, and the molecular formula is C8H11NO, COA of Formula: C8H11NO.
