5-dimethoxy-2-imidazolidinone derivatives, which are readily accessible from simple 1,3-dihydro-2-imidazolone heterocycles, represent good candidates for a new class of chiral synthons for use in the preparation of optically active threo-diamines such as 2S,3R- and 3S,4S-diamino carboxylic acids.
(4 S,5 S)-和(4 R,5 R)-1-酰基-4,5-二甲氧基-2-咪唑啉酮衍生物可从简单的1,3-二氢-2-咪唑啉酮杂环容易获得新型手性合成子的良好候选者,可用于制备旋光性苏二胺,如2 S,3 R-和3 S,4 S-二氨基羧酸。
