of (2S,4R)-5,5-dichloroleucine is reported in 13 steps from (S)-methyl 2-(hydroxymethyl)propanoate. A density functional J-based analysis of this compound and a comparison with that of its (2S,4S) epimer is also performed in order to complete our study of J-configurational assignments in 1,3-nitrogen-containing acyclic moieties.

据报道,从 (S)-2-(羟甲基) 丙酸甲酯分 13 个步骤合成 (2S,4R)-5,5-二氯亮氨酸。还对该化合物进行了基于密度泛函 J 的分析,并与其 (2S,4S) 差向异构体进行了比较,以完成我们对含 1,3-氮无环部分的 J-构型分配的研究。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
