A general protocol has been developed for the facile construction of titled derivatives via three component reaction between 3-substituted phenyl-1H-pyrazole-4-carbaldehyde, malononitrile and various Michael donors in presence of 5 mol% polystyrene supported 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene(PS-TBD). PS-TBD was reused for at least five runs with nearly constant catalytic activity. All compounds were screened for antimicrobial and antioxidant activities.

根据各方解读,2011年的中央一号文件之所以将水利工作的重要性提到了前所未有的高度,是由于决策层已经认识到:当高速公路、高速铁路已初具规模后,水利正在成为制约国民经济发展的短板,还有中国稀缺的农业资源三要素水土热中,只有“水”尚有潜力可挖。 这使整个水利行业群情激奋、热情高涨。但事实上,如何把中央一号文件落到实处,还有水权制度、耕地保护制度、水利工程管理模式、投资渠道的理顺及相关制约制衡机制的细
