1H n.m.r. studies of chiral porphyrins derived from meso-tetrakis-(2-amino-phenyl) porphyrins: simple proof of the absence of racemisation of the chiral amino acid residues during their synthesis
Abstract
1 H N.m.r. studies of bis-strapped chiral porphyrins derived from the meso-5,10,15,20-tetrakis(2-aminophenyl) porphyrin show that racemisation does not occur during their synthesis.
