Abstract

A facile and metal-free one-pot protocol for the synthesis of fused imidazopyridine scaffolds has been developed. This novel protocol combines the Groebke-Blackburn-Bienaymé reaction (GBBR) with a sequential TBAB-mediated cyclization cascade. Biological evaluation demonstrated that compound 6a inhibits human prostate cancer cell DU-145 proliferation with an IC50 of 1.6 μM. The molecular mechanism study indicates that 6a significantly suppresses the oncogenic Erk kinase phosphorylation at 3 μM.
