摘要：
An efficient and regioselective cyclization for construction of pyrazolo[3,4-b]pyridines and methylene-bridged bis(pyrazolo[1,5-a]pyrimidines) has been established. It involves a [3+2+1] annulation of 3(5)-aminopyrazole, N,N-dimethylethanolamine (DMEA), with 1,2-insertion of aryl methyl ketones or 2,1-insertion of aryl alkynes. DMEA is oxidized through C(sp3)-H activation to provide a single or triple carbon source.
