different halogenated benzenes yielded alkyne-bridged α-amino acids. A series of cationic mono- to hexanuclear (Ph3P)2Pt complexes with the anions of p-ethynylphenylalanine and alkynyl- or benzene-bridged di-, tri-, tetra- and hexa-ethynyl phenylalanines as N,O-chelate ligands was prepared. N-t-Boc-p-ethynylphenylalanine methyl ester was metal-substituted to give complexes of the types Ph3PAu-C≡C–R and (Et3P)2Pt(C≡CR)2
钯介导的对乙炔基苯丙氨酸 (p-epa) 与不同卤代苯的偶联产生炔桥连的 α-氨基酸。制备了一系列带有对乙炔基苯丙氨酸和炔基-或苯桥连的二、三、四和六乙炔基苯丙氨酸的阴离子作为 N,O-螯合配体的阳离子单到六核 (Ph3P)2Pt 络合物。Nt-Boc-p-乙炔基苯丙氨酸甲酯被金属取代,得到Ph3PAu-C≡C-R和(Et3P)2Pt(C≡CR)2类型的配合物。苯桥连的二、三、四和六对乙炔基苯丙氨酸甲酯与二茂铁醛形成席夫碱,从 Ph2PCH2CH2CH2NH2 和苯桥连的三乙炔基苯丙氨酸获得三足配体。(Ph3P)2Pt[NH2C(H)(CH2C6H4C≡CH)CO2]+BF4-的结构由X射线衍射确定。
