N-A-(2,4-二硝基-5-氟苯基)-L-丙氨酸 | N-(2,4-dinitro-5-fluorophenyl)-L-alaninamide | 95713-52-3 | C9H9FN4O5 | 272.193 |
We report the full structural determination of the depsipeptide petriellin A. The absolute configuration of the amino acid residues, N-methyl isoleucine and N-methyl threonine, have been determined by a combination of HPLC and TLC comparison of synthetic Marfey’s derivatives and Marfey’s derivatives of the natural product hydrolysate. The configuration of the chiral centres in these two N-methylated residues was found to be the same as those of the common unmethylated l-amino acids.
