Synthesis of optically pure δ-lactones by diastereomeric resolution was investigated. Amino acid derivatives, which can be obtained at a relatively low cost, were used as resolving agents. Six optically pure δ-lactones were efficiently synthesized using Cbz-L-alanine without other expensive resolving agents. Both enantiomers of δ-lactone obtained had over 98% enantiomeric excesses. This diastereomeric resolution is very efficient for the preparation of optically pure δ-lactones.
研究了通过非对映体拆分合成光学纯δ-内酯。使用可以以相对低成本获得的氨基酸衍生物作为拆分剂。在没有其他昂贵拆分剂的情况下,使用Cbz-L-丙氨酸高效合成了六种光学纯δ-内酯。所得到的δ-内酯的两种对映体的对映体过量均超过98%。这种非对映体拆分对于制备光学纯δ-内酯非常有效。
