A library of isomeric glutamic acid analogs based on the spiro[3.3]heptane skeleton is designed. Two members of the library, (R)- and (S)-2-amino-spiro[3.3]heptane-2,6-dicarboxylic acid hydrochlorides, were synthesized. The stereochemistry of the synthesized amino acids was determined using 1H–1H-NOESY of their diastereomeric derivatives. The aminocarboxylate moiety and the carboxylic group in the
设计了一个基于螺[3.3]庚烷骨架的异构谷氨酸类似物文库。合成了该库的两个成员,(R)-和(S)-2-氨基-螺[3.3]庚烷-2,6-二羧酸盐酸盐。使用测定中合成的氨基酸的立体化学1 H- 1其非对映体衍生物的H-NOESY。合成的谷氨酸类似物中的氨基羧酸盐部分和羧基由于具有刚性的螺环骨架而相对于彼此在空间上“固定”,因此,它们可用于探测不同谷氨酸受体的拓扑结构。
