    • The attempted recrystallization of O-pentafluorobenzoyloxime 2a under nitrogen atmosphere resulted into the formation of the trans-fused dihydroindole derivative trans-3a.

    • note
    • 13 it was reported that trans-3a was obtained quantitatively from O-pentafluorobenzoyloxime 2a after the purification with Merck silica gel 60N. However, this result was not reproducible. Other than the desired trans-3a (77%), as shown below, ketone (2%) and dihydroindole (ca. 5%) whose stereochemistry was not determined were detected as byproducts (Fig. 4). (diagram presented)

    • note
    • When radical initiators such as 2,2′-azobis(isobutyronitrile) and benzoyl peroxide were employed for the cyclization of O-pentafluorobenzoyloxime 2a, the cyclized product was obtained in low yield with many by-products.

    • The solvent dependency on the formation of indole 13 and 3a,7a-dihydroindole 14 was not clear. The example for the oxidation of 3a,7a-dihydroindole to indole is reported. See; D. Danion, B. Arnold, and M. Regitz, Angew. Chem., 93, 118 (1981).
