Palladium(0)-Catalyzed Heteroarylation of 2- and 3-Indolylzinc Derivatives. An Efficient General Method for the Preparation of (2-Pyridyl)indoles and Their Application to Indole Alkaloid Synthesis
the pyridine ring with subsequent electrophilic cyclization upon the indole 3-position from an appropriately N(b)-substituted 2-(2-piperidyl)indole, is reported. For this purpose, Pummerercyclizations have been extensively studied. Whereas the indole-unprotected sulfoxide 17 gives the corresponding indoloquinolizidine 19 in low yield and mainly undergoes an abnormalPummerercyclization that ultimately

Palladium-catalyzed coupling of 1-(tert-butyldimethylsilyl)-3-indolylzinc chloride (2) with either π-deficient or π-excedent heteroaryl halides gives 3-arylindoles in good to excellent yields. The method is extensively applied to the preparation of 3-(2-pyridyl)indoles.
