acids with primary and secondary amines under a variety of conditions (reflux, sealed tube, microwave) has been compared for a significant range of coupling partners of relevance to the preparation of amides of interest in pharmaceutical chemistry. Commercial microwave reactors promote the fastest couplings and allow the use of significantly sterically hinderedamines (primary and secondary) and carboxylic

comparable salen ligands, three synthesized CuIINaI-complexes present efficient catalytic activities for the coupling and cyclization reaction of 1,2-diaminopropane with nitriles towards 2-imidazolines. The catalytic results show that salen ligands with an electron-donating substituent and small sterichindrance improve the catalytic activity.
基于各种可比的塞伦配体,三种合成的Cu II Na I配合物为1,2-二氨基丙烷与腈的偶合和环化反应提供了对2-咪唑啉的有效催化活性。催化结果表明,具有供电子取代基和小位阻的萨伦配体提高了催化活性。
Layered Double Hydroxides as Reusable Catalysts for Cyclocondensation of Amidines and Aminoalcohols: Access to Multi-functionalized Oxazolines
An efficient catalytic protocol based on reusable MgAl-layered double hydroxides has been developed for the synthesis of multi-functionalized oxazolines via the cyclocondensation of amidines and aminoalcohols. The developed method has a broad substrate scope and excellent functionalgroup tolerance and uses a reusable catalyst. The catalyst can be conveniently recycled by filtration and reused for
