Comparison of the 1H and 13C nmr spectroscopic data of the synthetic amino acids with that reported for the naturally occurring material indicates that the relative stereochemisuy of the AHDA found in microginin is syn. The absolute stereochemistry of the natural amino acid is shown to be (2S,3R) by comparison of its reported CD spectrum with that recorded for the synthetic material prepared herein.
3-氨基-2-羟基癸酸(AHDA)是一种不寻常的氨基酸,据说发生在最近分离的血管紧张素转化酶抑制剂microgipin中。为了阐明天然存在的物质的立体化学,从而完成微紫精的结构分配,AHDA的(2 R,3 R)-反-非对映异构体和(2 S,3 R)顺-非对映异构体均已被采用。准备好了。合成氨基酸的1 H和13 C nmr光谱数据与天然物质报道的数据比较表明,在微ginin中发现的AHDA的相对立体化学为SYN。通过比较其报告的CD光谱与本文制备的合成材料所记录的CD光谱,天然氨基酸的绝对立体化学显示为(2 S,3 R)。
