Highly Functionalized Organolithium Reagents for Enantiomerically Pure α-Amino Acid Synthesis
摘要:
Highly functionalized L-serine-derived organolithium reagents have been generated and reacted with a variety of electrophiles, delivering novel enantiomerically pure adducts. These adducts were then converted into homochiral amino alcohols and novel nonproteinogenic alpha-amino acids, including an aspartic acid mimic that has been synthesized in an enantiomerically pure form for the first time.

organolithium reagents derived from l-serine have been generated and reacted with electrophiles. The novel enantiomericallypure adducts thus obtained were then converted, through β-amino alcohols, into novel non-proteinogenic α-aminoacids. The methodology also made available a novel boronic acid which was then employed as a Suzuki cross-coupling partner, elaborating a new pathway to phenylalanine analogues
