Abstract A stereocontrolled approach to functionalized acyclic β 2, 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. This stereospecific and ...
