Pd(II)-catalyzed
addition of sp2 C–H to nitrile/aerobic
oxidation sequences for the preparation of functionalized α-imino
ketones is described in which readily available heteroarenes and O-acyl cyanohydrins were employed. Various functionalized
targeted molecules can be prepared in good yields with high atom and
step economy. Moreover, a broad substrate scope and the ready manipulation
and availability of the reaction partners enable this protocol to
be appealing to explore the chemical space of the construction of
functionalized α-imino ketones with high efficiency.
