This paper describes the mon-, di-, and triarylation of the pyrimidine ring. It is possible to introduce one or more aryl rings in generally good yields and in a specific order, namely first in position 4, second in position 6, followed by position 2. A study of solvent and catalyst requirements has also been conducted.

arylboronic acids was evaluated and determined to suffer from the formation of large amounts of boronicacidhomocoupling products in conjunction with dehalogenation. Homocoupling product formation in this process likely occurs through a rare protonolysis/second transmetalation event rather than by the well-established mechanism requiring the involvement of O2. The scope of this boronicacid homocoupling

Routes to bicyclic tetramates derivedfrom cysteine permitting ready incorporation of functionality at two different points around the periphery of a heterocyclic skeleton are reported. This has enabled the identification of systems active against Gram-positive bacteria, some of which show gyrase and RNA polymerase inhibitory activity. In particular, tetramates substituted with glycosyl side chains
报道了从半胱氨酸衍生的双环四甲酸酯的路线,允许在杂环骨架周围的两个不同点处随时掺入功能。这使得能够鉴定出对革兰氏阳性菌具有活性的系统,其中一些系统显示出旋转酶和 RNA 聚合酶抑制活性。特别是,被糖基侧链取代的四酸酯(选择赋予极性和水溶性)在两种情况下显示出高抗菌活性和适度的旋转酶/聚合酶活性。理化性质分析表明,抗菌活性四甲酸酯通常占据MW为300-600、clog D7.4为-2.5至4和rel.的理化空间。 PSA 为 11-22%。这项工作表明,通过操纵四甲酸酯骨架可以轻松获得具有生物活性的 3D 文库。
