Photoreaction of N-(ω-indol-3-ylalkyl)phtalimides (1a and 1c) gave oxetoindoles (3a and 3c), the first example of oxetane formation of the aromatic imide carbonyl in the Paterno-Buechi reaction.

Upon irradiation in acetone, N-(ω-indol-3-ylalkyl)phthalimides (1, n=2-5) underwent intramolecular Paterno-Buechi reaction to give oxetoindoles or their ring-opening products.However, N-(ω-indol-2-ylalkyl)phthalimides (9, n=2,3) yielded not the oxetane, but the N-deacetylated compounds.Keywords-intramolecular photocyclization; indolylalkylphthalimide; oxeto-indolone; Paterno-Buechi reaction; imide-oxetane; photoreaction
