involvement of a chelation-controlled TS. The synthesis of functionalized 1,4-diols, cis piperidine-2,3-dicarboxylate derivative and β-ethyl aspartic acid hydrochloride was performed using the N-substituted β-vinyl aspartates obtained in this work. The stereochemistry of representative products was unambiguously established from the single crystal X-ray structure analyses.
