malondlaldehyde Is capable of modifying amino acid residues to novel, highly fluorescent 1,4-dihydropyridines. The structures assigned to these compounds are supported by UV, HRMS, high-field NMR, and X-ray crystallographic data. The mechanism of these transformations, which Is fully discussed, involves the Michael reaction of alkylidene malondialdehydes with enaminals, both of which are produced as detectable
在合适的条件下,丙二醛能够将氨基酸残基修饰为新型的高荧光1,4-二氢吡啶。分配给这些化合物的结构受到UV,HRMS,高场NMR和X射线晶体学数据的支持。充分讨论了这些转化的机理,涉及亚烷基丙二醛与烯胺的迈克尔反应,二者均以可检测的中间体形式产生。这些发现对于解释丙二醛的某些生物化学可能具有重要意义。该转化也提供了一种新的合成方法,该方法可以合成广泛潜在的作为钙通道拮抗剂的光稳定的4-芳基化的1-芳基-1,4-dlhydropyridines。
