S N 2' sequences have been employed for the synthesis of β-branched α-amino acids using 1,2-diastereocontrol for forming C―C bonds. An oxazolidine fragment derived from Garner's aldehyde provides the handle for facial discrimination and acts as a masked amino acid functionality. This study encompasses directed and non-directed allylic substitution reactions. The stereocontrol of the oxazolidine appendage
SN 2' 序列已用于合成 β-支链 α-氨基酸,使用 1,2-非对映控制形成 C-C 键。来自 Garner 醛的恶唑烷片段提供了面部识别的手柄,并充当了掩蔽的氨基酸功能。该研究包括定向和非定向烯丙基取代反应。还研究了末端烯烃加氢甲酰化过程中恶唑烷附属物的立体控制。公开了了解反应的非对映化学结果以及合成应用的努力。
