of the complexes under phase transfer catalyzed alkylations with hydroxide bases, as well as the DBU catalyzed Michael Additions of optically active 3′-substituted-2-oxazoladinone amides of unsaturated carboxylic acids. It was found that the trifluoromethyl containing nucleophilic glycine equivalents were more reactive than their non-trifluoromethyl analogues in both reaction types. Therefore, the application
将介绍几种Ni(II)配合的甘
氨酸Schiff碱的合成制备方法,以及对其反应性和实用性的研究。这些研究的关键是在稳定由甘
氨酸组分衍生的烯醇化物的共轭体系框架内引入吸电子三
氟甲基。在相转移催化的与氢氧化物碱的烷基化反应下,以及在不饱和
羧酸的旋光性3'-取代-2-
恶唑烷酮酰胺的
DBU催化的迈克尔加成反应下,对每种络合物的反应性进行了评估。发现在两种反应类型中,含三
氟甲基的亲核甘
氨酸当量比其非三
氟甲基类似物更具反应性。因此,
