Herein an one-pot protocol for visible light-induced synthesis of functionalized spirocyclic indolines I [R = P(O)Ph2, 2-pyrrolyl, 3-indolyl, etc.; R1 = H, 5-F, 6-Me, etc.] was described under mild conditions by means of a process involving sequential difluoromethylative dearomatization, hydroxylation and substitution reactions of indole derivatives The transformation proceeded via a hydroxylated “”acetal pool”” intermediate that could react with various nucleophiles. Several of the phosphine-oxide and indole-substituted products showed good fungicidal activity, suggesting that this protocol might be useful in the agrochem. field. The results came from multiple reactions, including the reaction of fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Name: fac-Tris(2-phenylpyridine)iridium)
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Name: fac-Tris(2-phenylpyridine)iridium
