A variety of polyfunctionalized pyridines were synthesized from readily available ketones with α,β-unsaturated aldehydes and ammonium acetate under a mild organocatalyst.
通过使用易于获得的酮与α,β-不饱和醛和醋酸铵,在温和的有机催化剂下,合成了多种多官能团化的吡啶。
Herein we report an interesting multicomponent reaction of α,β-unsaturated aldehydes, 2-hydroxy-1,4-naphthoquinone and 5-aminopyrazoles by liquid assisted grinding.
