  Abstract Extremely facile and efficient procedures have been developed for the synthesis of dihydropyrrol-2-ones and highly substituted piperidines. One-pot four-component reaction of amines, dialkyl acetylenedicarboxylates, and formaldehyde in the presence of ethylenediammonium diformate in ethanol under reflux conditions provides N-aryl-3-amino dihydropyrrol-2-one-4-carboxylates in good to high yields

  摘要 对于二氢吡咯-2-酮和高度取代的哌啶的合成，已经开发了极其简便和有效的方法。胺，乙炔二羧酸二烷基酯和甲醛在乙二酸二铵存在下于乙醇中在回流条件下进行一锅四组分反应，可提供高收率的N-芳基-3-氨基二氢吡咯-2-一-4-羧酸酯。发现相同的条件可用于通过胺，醛和β-酮酸酯的三（伪五）组分反应合成高度取代的哌啶。发现该催化剂是可重复使用的并且可以使用多达五次而不会显着降低其活性。 图形概要

• A novel class of small-molecule caspase-3 inhibitors prepared by multicomponent reactions

  A series of tetra- and pentasubstituted polyfunctional dihydropyrroles 5 and 6 were synthesized via practical multicomponent reactions (MCRs) for research on their structure activity relationship as caspase-3 inhibitors. Among 39 compounds evaluated, 14 of them exhibited inhibition against caspase-3 with IC50 ranging from 5 to 20 mu M. The inhibitory activities of 5 and 6 depend on the nature of substituents on different positions. 5 and 6 possess a different scaffold from those previously reported and are the first caspase-3 inhibitors prepared via MCRs. The most active compounds 5k (IC50 = 5.27 mu M) could therefore be used as a lead for the development of highly potent caspase-3 inhibitors as drug candidates for therapeutic agents by taking advantage of MCRs.
