Application of the asymmetric chelate enolate Claisen rearrangement to the synthesis of unsaturated polyhydroxylated amino acids

摘要

Ester enolate Claisen rearrangement of chelated N-protected chiral allylic amino acid esters results in the formation of polyhydroxylated gamma,delta-unsaturated amino acids in good yields and with a high degree of chirality transfer. [References: 38]
