A convergent synthetic methodology has been developed to access both (2S)- and (2R)-3-fluoroalanine and their corresponding N-methyl analogues, in optically pure form, through a common oxazolidinone intermediate that can be obtained from L- or D-serine. In addition, a procedure for incorporation of these unnatural amino acids in peptide scaffolds is also disclosed herein that minimizes the occurrence
已开发出一种收敛的合成方法,以通过可从L-或D-获得的常见恶唑烷酮中间体获得光学纯净形式的(2S)-和(2R)-3-氟丙氨酸及其相应的N-甲基类似物丝氨酸。另外,本文还公开了将这些非天然氨基酸掺入肽支架中的方法,其使酰胺键形成过程中β-消除的发生最小化。[反应:看文字]
