Synthesis of 1,2,3,9b-Tetrahydro-9b-hydroxy-1-phenylpyrroloisoindol-5-one via the Hydrazinolysis of 2-Phenyl-2-(2-phthalimidoethyl)indan-1,3-dione

Hydrazinolysis of 2-phenyl-2-(2-phthalimidoethyl)indan-1,3-dione gave 1,2,3,9b-tetrahydro-9b-hydroxy-1-phenylpyrroloisoindol-5-one via the conversion of 2-(2-aminoethyl)-2-phenylindan-1,3-dione into the carbinolamine which underwent ring expansion followed by a transannular cyclisation.

Photochemistry of N-(2-Alkenyl)phthalimides. Photoinduced Cyclization and Elimination Reactions

The photochemical reactions of N-(2-alkenyl)phthalimides 4a-f were examined.Irradiation of a solution of 4a,b,d,f in methanol yielded a mixture of the methanol-incorporated cyclization products 5a + 6a, 13a-d, 15a + 16a, and 23 + 24, respectively.Chemical
