mechanistic proposal, a new and rapid asymmetricsynthesis of (R)- and (S)-2-aminoalkanesulfonic acids from chiral amino alcohols was developed. Chiral amino alcohols were converted to chiral aziridines through the Wenker method or Mitsunobu reaction and the resulting aziridines were reacted with sodium bisulfite to produce chiral α-amino alkanesulfonic acids.

Chiral hydroxy- and aminohydroxysulfonic acids are widespread in the marine and terrestrial environment. Here we report simple methods for the synthesis of d- and l-cysteinolic acid (from (Boc-d-Cys-OH)2 and (Boc-l-Cys-OH)2, respectively), R- and S-3-amino-2-hydroxypropanesulfonate (from S- and R-epichlorohydrin, respectively), and R- and S-2,3-dihydroxypropanesulfonate (from S- and R-epichlorohydrin
手性羟基和氨基羟基磺酸广泛存在于海洋和陆地环境中。在这里,我们报告了合成d - 和l -半胱氨酸(分别来自 (Boc- d -Cys-OH) 2和 (Boc- l -Cys-OH) 2)、R - 和S -3-的简单方法氨基-2-羟基丙磺酸盐(分别来自S-和R-表氯醇),以及R-和S -2,3-二羟基丙磺酸盐(分别来自S-和R-表氯醇)。d-半胱氨酸胆汁盐是通过与胆酸和鹅去氧胆酸偶联产生的。一系列单晶 3D X 射线结构证实了氨基磺酸盐的绝对构型。通过比较旋光度,我们将来自Gateloupia livida的天然存在的 3-氨基-2-羟基丙磺酸盐指定为具有R构型。这种简单的合成方法将支持未来对这些烷基磺酸盐的发生、化学分类分布和代谢的研究。
