SDS of cas: 98-97-5. The Name is Pyrazine-2-carboxylic acid. Through research, I have a further understanding and discovery of 98-97-5
The first total synthesis of echinomycin (1) was accomplished by featuring the late-stage construction of the thioacetal moiety via Pummerer rearrangement and simultaneous cyclization, as well as two-directional elongation of the peptide chains to construct a C2-symmetrical bicyclic octadecadepsipeptide bridged with a sulfide linkage. This strategy can be applicable to a variety of echinomycin analogues.
SDS of cas: 98-97-5. Bye, fridends, I hope you can learn more about C5H4N2O2, If you have any questions, you can browse other blog as well. See you lster.
