One-pot/four-step/palladium-catalyzed synthesis of indole derivatives: The combination of heterogeneous and homogeneous systems
One-pot, four-step syntheses of indoles using both solid-supported heterogeneous and homogeneous palladium catalysts and reagents were carried out. Such a combination of these two-phase catalysts and reagents causes a dramatic increase in yield, and it is a simple process. The presented methodology is effective for four-step reactions to provide various functionalized indoles.
PALLADIUM-CATALYSED COUPLING OF ARYL AND VINYL TRIFLATES OR HALIDES WITH 2-ETHYNYLANILINE: AN EFFICIENT ROUTE TO FUNCTIONALIZED 2-SUBSTITUTED INDOLES
The palladium(O)-catalysed coupling of aryl and vinyl triflates or halides with the easily available 2-ethynylaniline, followed by a palladium(II)-catalysed cyclization step, provides an efficient and very versatile procedure for the synthesis of function
