Synthesis and Spectrum of Chiral Boc Protected Amino Acids Linked Porphyrins

Abstract

Abstract: Meso-tetrakis(o-BocAlamido) porphyrin [H₂T(o-BocAla)APP, 1] and its zinc complex [ZnT(o-BocAla)APP, Zn-1, meso-tetrakis(o-BocThrmido)porphyrin [H₂To-ocAls)APP, and its zinc complex [ZnT(o-BocThr)APP, Zn-2 , meso-tetrakis(o-BocTyrmido) porphyrin [H₂T(o-BocTyr)APP, 3and its zinc complex [ZnT(o-BocTyr)APP, Zn-3] were synthesized and characterized by elemental analyses, FTIR, ¹HNMR, UV-Vis and CD.The FTIRspectra and ¹HNMR of these complexes were compared and discussed.The UV-Vis and CDspectra of complexes were also attributed and minutely discussed.Compared with ZnTPP, the bands of porphyrins 1, 2, 3 have visibly red-shifts.Obviously, the cotton signals of 1 and 2, 3 are opposite, maybe it was caused by hydroxyl group.

Key words: Chiral amino acids linked porphyrin, Synthesis, Property, Circular dichroism
