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.

SYNTHESIS OF HOMOCHIRAL HYDROXY-α-AMINO ACID DERIVATIVES

Treatment of N-phthaloyl-α-amino acid methyl esters with N-bromosuccinimide, followed by reaction with silver nitrate in aqueous acetone, affords homochiral hydroxy-α-amino acid derivatives, the stereochemistry of which is predetermined by that of the starting amino acids.
