Palladium catalysed tetramolecular queuing cascades of aryl iodides, carbon monoxide, amines and a polymer supported allene
Abstract
Chemo- and regio-specific palladium catalysed four component processes, involving formation of 3 new bonds, initiated by oxidative addition of Pd(0) with aryl iodides followed by sequential incorporation of CO (1 atm), a polymer supported allene and an amine provides complex heterocycles with 3 points of diversity in good yield and excellent purity after cleavage.
