(2S, 3S, 4S)-4-Amino-2,3-epoxy-1-alkanol gave 4-amino-1,3-alkanediol or 3,4-imino-1,2-alkanediol with Dibal or Ti(O-i-Pr)4 respectively and, after introduction of Boc group to its amino group, afforded a 4-amino-1,2,3-alkanetriol derivative under the influence of Ti(O-i-Pr)4.
(2 S,3 S,4 S)-4-氨基-2,3-环氧-1-链烷醇与丁二醛或Ti生成4-氨基-1,3-链烷二醇或3,4-亚氨基-1,2-链烷二醇(O- i- Pr)4,并且在将Boc基团引入其氨基后,在Ti(O- i- Pr)4的影响下得到4-氨基-1,2,3-链烷三醇衍生物。
