A stereocontrolled approach to functionalized acyclic β2,3-amino acid derivatives was accomplished from cis- or trans-2-aminocyclohexenecarboxylates derived from bicyclic β-lactam regioisomers. The transformations were based on oxidative ring cleavage through the ring C–C double bond of the cyclohexene β-amino esters, followed by functionalization of the dialdehyde intermediates with different phosphoranes
甲立体控制的方法来官能化无环β 2,3 -氨基酸衍生物从被完成顺-或反式从双环β内酰胺衍生的区域异构体-2-aminocyclohexenecarboxylates。转化基于环己烯β-氨基酯的环CC双键的氧化环裂解,然后用不同的磷烷将二醛中间体官能化。这种立体特异性和立体控制过程应用于合成无环β 2,3-氨基与酯,腈,酮基,烷基或芳基烷基官能酸衍生物。
