A stereospecific synthesis of both enantiomers of the marine alkaloid eudistomin X using the amino acid chiral pool is achieved. Comparison of 1H and 13C NMR chemical shifts of the synthetic product as either the free base, mono-salt or disalt with those reported for the natural product established that the ascidian metabolite was originally characterised as a mono-salt and that the absolute configuration
使用氨基酸手性库实现了海洋生物碱eudistomin X的两个对映异构体的立体定向合成。将合成产物以游离碱,单盐或二盐形式进行的1 H和13 C NMR化学位移与天然产物的报道进行比较,确定了海鞘代谢物最初被表征为单盐,并且其绝对构型是(10 R)。
