7,5-融合的氮杂双环烷骨架在内酰胺环的C3位置带有一个立体立体中心,可以作为有效的反向模拟,并已被证明是制备基于Arg-Gly-Asp(RGD)的环五肽的有用中间体(的cRGD)以纳摩尔活性α v β 3 /α v β 5整联蛋白拮抗剂。在这里,我们报告了新的氮杂双环烷骨架的合成,该骨架在C6位具有对位取代的苯乙基侧链,可用于获得基于cRGD的生物结合物,这些结合物可能在抗癌治疗中有希望的应用。通过在苯乙烯衍生物的存在下进行多米诺交叉烯炔复分解/闭环复分解(CEYM / RCM),然后对二烯系统进行催化加氢,我们可以轻松地将二肽前体转化为所需的C6官能化的氮杂双环烷烃骨架。脱保护后,可以利用在苯乙烯部分上适当保护的对氨基的存在,以直接缀合生物活性化合物或在cRGD单元和生物活性化合物之间引入合适的间隔基。

Copper(salen) complex 1 has been found to catalyse the asymmetric alkylation of enolates derived from a variety of aminoacids. There is a clear relationship between the size of the side chain in the substrate and the enantioselectivity of the process, so that the enantioselectivity decreases in the order alanine>aminobutyric acid>allylglycine>leucine>phenylalanine>valine.
