Abstract
An efficient synthesis of pyrazolo[4,3-c]quinolin-4-ones and indolo[3,2-c]quinolin-6-ones has been achieved by the photocyclization of 5-chloro-N-phenyl-1H-pyrazole-4-carboxamides and 2-chloro-N-phenyl-1H-indole-3-carboxamides in acetone.
Key words
photocyclization - pyrazolo[4,3-c]quinolin-4-one - indolo[3,2-c]quinolin-6-one - 5-chloro-N-phenyl-1H-pyrazole-4-carboxamides - 2-chloro-N-phenyl-1H-indole-3-carboxamides
