A stereocontrolled synthesis of protected variants 13 and 15 of HPmp 2, a mimic of phosphorylated tyrosine, was achieved through either chiral-auxiliary assisted or chiral heterobimetal catalyzed stereoselective hydrophosphonylation of 4-formyl-l-phenylalanine derivative 7. Fluorination of HPmp derivatives 13 and 15 thus obtained was carried out to give FPmp derivatives 16 and 17.
通过手性助剂或手性异双金属催化的4-甲酰基-1-苯丙氨酸衍生物7的立体选择性氢膦酰化作用,实现了HPmp 2的保护变体13和15的磷酸化酪氨酸的模仿体的立体控制合成。进行由此获得的HPmp衍生物13和15的氟化,得到FPmp衍生物16和17。
