A Tandem Ring Opening/Closure Reaction in A BF3-Mediated Rearrangement of Spirooxindoles
Treatment of the readily accessible spiro-cyclohexadienones from the PhI(OCOCF3)2-mediated spiro-cyclization of N-substituted benzanilides, with BF3?Et2O initiates a tandem ring opening/closure reaction leading to the formation of the biologically interesting 8-hydroxy-phenanthridin-6(5H)-one compounds. This unique rearrangement pattern involves the ?migration? of the electron-deficient N-methyl carbamoyl moiety rather than the electron-rich aryl group as observed and reported previously in all other similar transformations. (Figure presented.).
