摘要：

Oxidative photocyclizations of appropriate 2-anilino alkenenitriles (6) afforded a series of indole-2-carbonitriles (7) having bromoalkyl substituents at the C-3 positions. Upon treatment with Bu3SnH, these indolecarbonitriles underwent intramolecular cyclizations either by attack at the C-3 positions of the indole rings to give the spiro-annelated indolinecarbonitriles or by attack at the cyano group to give carbazolone derivatives.
