摘要：

A three-component bicyclization strategy for the efficient synthesis of densely functionalized pyrazolo[3,4-d]thiazolo[3,2-a]pyrimidines from readily accessible aryl aldehydes, -thiocyanate ketones, and pyrazol-5-amines was established. The reaction pathway involves a nucleophilic addition/5-exo-trig/6-endo-trig bicyclization sequence that results in continuous multiple bond-forming events, including the formation of C-N and C-C bonds, to give high levels of molecular complexity.
