Concise synthesis of all stereoisomers of β-methoxytyrosine and determination of the absolute configuration of the residue in callipeltin A

(Chemical Equation Presented) All stereoisomers of β-methoxytyrosine (β-OMeTyr), a stereo-undefined component of callipeltin A, were synthesized from L- and D-tyrosine. The stereochemistry of β-OMeTyr in callipeltin A was determined to be 2R,3R by an oxidative procedure and Marfey's analysis.
