N-(p-Toluenesulfonyl)glycine o-phenolamide (3a) and the analogous derivatives of d,l-alanine (3b), L-valine (3c), L-leucine (3d), and L-phenylalanine (3e) were synthesized in yields >80% by condensation of N-(p-toluenesulfonyl)amino acyl chlorides with o-aminophenol. The structure and conformation of these amides were established by NMR spectroscopy and X-ray crystallography. © 2003 Wiley Periodicals
N-(对甲苯磺酰基)甘氨酸邻苯酚酰胺 (3a) 和 d,l-丙氨酸 (3b)、L-缬氨酸 (3c)、L-亮氨酸 (3d) 和 L-苯丙氨酸 (3e) 的类似衍生物是通过 N-(对甲苯磺酰基)氨基酰氯与邻氨基苯酚的缩合,以 >80% 的产率合成。这些酰胺的结构和构象是通过核磁共振光谱和 X 射线晶体学确定的。© 2003 Wiley Periodicals, Inc. 杂原子化学 14:247–253, 2003; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.10135
