摘要:
Lipase PS catalyzed acetylation of prochiral 2-(omega-phosphono)alkyl-1,3-propanediols 1a-c was found to proceed with high enantioselectivity. The applications of phosphonic chirons 2a-c thus obtained were illustrated by the stereocontrolled synthesis of omega-phosphono-alpha-amino acids such as L-AP-3, L-AP-4, and N-Boc-L-F(2)Pab(OEt)(2)-OH.
