نویسندگان

چکیده

A green and sustainable nitrone formation reaction via visible-light-promoted of aryl diazoacetates with nitrosoarenes is described. This protocol exhibits good functional group tolerance broad substrate scope for both nitrosoarenes. Comparing the reported methods synthesis nitrones from nitrosoarenes, described herein occurs under sole visible-light irradiation without need any catalysts additives.

Synthesis of quinazolinimines and quinazolinamines from 2-fluorobenzonitriles under catalyst-free conditions.

A convenient procedure for the synthesis of quinazolinimines and quinazolinamines from 2-fluorobenzonitriles has been developed. By using KO(t)Bu as the promotor with 2-aminopyridines or amidines as the reaction partner, the desired heterocycles were produced in moderate to good yields under catalyst-free conditions.
