Abstract

An efficient tandem radical process comprising a thermal alkoxyamine homolysis, an isonitrile trapping reaction, a 5-exo-trig cyclization, and a homolytic aromatic substitution leads to substituted dihydroquinolines. Depending on the substituent R1, oxidation to dihydro-1 H-cyclopenta [b] quinolines (for R1= aryl) or tautomerization to tetrahydro-1 H- cyclopenta [b] quinolines (for R1= CO2Me, CN) occurs. The heterocycles are obtained in ...
