|Title:||Applications of carbon-nitrogen bond cleavage reaction: A synthesis/derivatisation of 11H-indeno[1,2-c ]isoquinolines|
Gidwani, Ramesh M
|Abstract:||Orthophosphoric acid HCOOH treatment of 3-( 4,5-dimethoxy-2-vinylphenyl)-1(2H)-isoquinolinone 5a and 6,7- dimethoxy 3-(4,5-dimethoxy-2-vinylphenyl)-1(2H)-isoquinolinone 5b brings about cyclization to give the indeno-[1,2-c]isoquinolines 6a and 6b. Reaction with POCI3 produces the chloro compounds. Hydrogenolysis gives the dechlorinated products 8a and 8b. Reaction of chloro derivatives with different amines gives the amino substituted 11H-indeno-[1,2-c] isoquinolines 9 and 10.|
