Gold-Catalyzed 1,2-Oxoarylations of Nitriles with Pyridine-Derived Oxides
摘要:
AbstractWe report the first success in the gold‐catalyzed oxoarylations of nitriles with pyridine‐derived N‐oxides using gold carbenes as initiators. These oxoarylations were also achieved satisfactorily in intermolecular three‐component oxidations, including diverse alkenyldiazo esters, nitriles, and pyridine‐based oxides.
Compounds of the formula (I), in which R1, R2 and R3 have the meanings indicated in Claim 1, are kinase inhibitors and can be employed, inter alia, for the treatment of tumors.

This work reports an efficient synthesis of novel benzo[7,8]indolizino[2,3,4,5-ija]quinazoline derivatives between 2-(2-ethynylaryl)acetonitriles 1 and anthranils 2. The synthetic approach involves the initial formation of 7-formylindole intermediates that can be implemented by DBU to activate a novel indole–nitrile–aldehyde cyclization.
