This invention relates to a method for the production of a sphingoid base according to formula
1
comprising the steps of
(1) dissolving a starting compound according to formula III or a salt thereof in a substantially inert solvent,
2
(2) protecting the NH
2
group with a NH
2
protecting group,
(3) activating the C-4 HR
3
group for an elimination reaction with the C-5 HR
4
group,
(4) causing an elimination reaction to take place to form a double bond between the C-4 and C-5 carbon atom, and
(5) removing the NH
2
protecting group.
这项发明涉及一种生产按照公式1的鞘氨醇基的方法,包括以下步骤:(1)在一种基本惰性溶剂中溶解公式III或其盐的起始化合物,(2)用NH2保护基保护NH2基团,(3)激活C-4 HR3基团以进行与C-5 HR4基团的消除反应,(4)引起消除反应以形成C-4和C-5碳原子之间的双键,(5)去除NH2保护基。
