Several precursors of unnatural amino acids have been synthesized by addition of vinyl sulfones to an imine derived from (R)-glyceraldehyde. In these reactions the addition not only takes place in a stereoselective way, but a hydride transfer is also produced giving rise to the saturated sulfones and a new imine.
通过将

亚胺上,已经合成了几种非天然
氨基酸的前体。在这些反应中,加成不仅以立体选择性方式发生,而且还产生
氢化物转移,从而产生饱和砜和新的
亚胺。
