Acrylic acids and alanines substituted with heteroaryl groups at the beta-position were synthesized and spectroscopically characterized (UV, HRMS, (1)H NMR, and (13)C NMR spectroscopy). The heteroaryl groups were furanyl, thiophenyl, benzofuranyl, and benzothiophenyl and contained the alanyl side chains either at the 2- or 3-positions. While the former are good substrates for phenylalanine ammonia-lyase
合成了在β位置被杂芳基取代的丙烯酸和丙氨酸,并进行了光谱表征(UV,HRMS,(1)H NMR和(13)C NMR光谱)。杂芳基基团是呋喃基,噻吩基,苯并呋喃基和苯并噻吩基,并且在2-或3-位含有丙酰基侧链。前者是苯丙氨酸解氨酶(PAL)的良好底物,而后者是抑制剂。例外的是噻吩-3-基丙氨酸(一种中等的底物)和呋喃-3-基丙氨酸(惰性)。讨论了这些例外的可能原因。从外消旋杂芳基-2-丙氨酸开始,它们的D-对映异构体通过立体破坏方法制备。由杂芳基-2-丙烯酸酯以高氨浓度制备杂芳基-2-丙氨酸的L-对映异构体。
