3-oxazolidine (4-oxaproline) derivatives starting from serine and threonine is described which avoids the use of toxic solvents or reagents. Elaboration of these compounds allows significant improvement in the handling of serine and threonine during the multigram preparation of oligopeptide structures and affords versatile chiral building blocks for the organic synthesis.
描述了一种非常简单的从丝氨酸和苏氨酸开始制备手性旋光性N-保护的4-羧基-1,3-恶唑烷(4-氧杂脯氨酸)衍生物的方法,该方法避免了使用有毒溶剂或试剂。这些化合物的精制可以在多肽寡糖结构制备过程中显着改善丝氨酸和苏氨酸的处理,并为有机合成提供了通用的手性结构单元。
