All stereoisomers of beta-methoxytyrosine (beta-OMeTyr), a stereo-undefined component of callipeltin A, were synthesized from L- and D-tyrosine. The stereochemistry of beta-OMeTyr in callipeltin A was determined to be 2R,3R by an oxidative procedure and Marfey's analysis. [structure: see text]
β-甲氧基酪氨酸(β-OMeTyr)是callipeltin A的一种立体构型未明确的成分,其所有立体异构体均由L-酪氨酸和D-酪氨酸合成。通过氧化法和马尔费伊分析法确定了callipeltin A中β-OMeTyr的立体化学结构为2R,3R。[结构:见正文]
