Indole, 2-homoallyl

Pentenenitriles and benzo[f]indoles. Ally iminophosphoranes are formed from the corresponding azides upon treatment with PPh j (Staudinger reaction). Condensation of these products with diaryl ketenes leads to 4-pentenenitriles by a sig-matropic rearrangement. In the homoallyl series the Wittig reaction is followed by an intramolecular Diels-Alder reaction. Mild dehydrogenation of the products gives ben zo[/] indoles. ... [Pg.386]

Cobalt NHC catalysts have been reported to promote intramolecular olefin hydroary-lation of Ai-homoallyl indoles (158), having a C(3) aldimine directing group, to afford the 5-mco-trig (159) and 6-enr/o-trig (160) products. The course can be controlled by the choice of the NHC ligand. [Pg.422]
