Abstract

Synthesis of polysubstituted 2-methylene-1,2-dihydropyridines were accomplished by one-pot multicomponent reaction of 3-formylchromones, anilines and aliphatic 1,3-diones under catalyst and solvent-free reaction conditions. The reaction proceeds via Schiff base mediated, Michael addition followed by ring opening/ring closure sequential process resulting two new C–N and one C–C bonds formation. Neat reaction conditions and higher yields are the advantages of the protocol.

多取代2-亚甲基-1,2-二氢吡啶的无溶剂催化合成

在无催化剂和无溶剂的条件下，以3-甲酰基色酮、苯胺和脂肪族1,3-二酮为原料，通过一锅多组分反应合成了多取代2-亚甲基-1,2-二氢吡啶。反应通过席夫碱介导，迈克尔加成，开环/闭环的顺序过程进行，形成两个新的C-N键和一个C-C键。该工艺的优点是反应条件简单，产率高。

期刊介绍： Synthetic Communications presents communications describing new methods, reagents, and other synthetic work pertaining to organic chemistry with sufficient experimental detail to permit reported reactions to be repeated by a chemist reasonably skilled in the art. In addition, the Journal features short, focused review articles discussing topics within its remit of synthetic organic chemistry.
