Synthesis of novel 9-(1-iodovinyl)acridin-(2H)-one through iodine mediated cascade 6-endo-dig cyclization followed by condensation and 3,3-sigmatropic migration of 2-aminophenyl propynyl oxyenone

An efficient and rapid synthetic strategy for the construction of a pharmaceutically important acridinone scaffold via cascade iodocyclization of functionally substituted 2-aminophenyl propynyl oxyenone is developed.
