Palladium-catalyzed synthesis of 3-alkoxysubstituted indoles
摘要:
Indoles having an electron-donating alkoxy-group in the 3-position were prepared from 1-(2-nitrophenyl)-l-alkoxyalkene derivatives via a palladium-catalyzed reductive N-heteroarmulation using carbon monoxide as the ultimate reducing agent. The required starting materials were prepared by a Stille coupling of 2-balonitroarenes with tributyl(1-ethoxyethenyl)stannane or tributyl(3,4-dihydro-2H-pyran-6-yl)stannane. (c) 2006 Elsevier Ltd.
