The study focuses on the synthetic construction of the BCDF ring system of ristocetin A, a glycopeptide antibiotic, using ruthenium-promoted intramolecular SNAr reactions. The researchers aimed to develop a method for constructing the 16-membered BCD model macrocycle of ristocetin A, which includes the required arylserine residue as the C ring and a fully functionalized F ring. Key chemicals used in the study include chlorocinnamic esters, N-Boc-protected arylserines, ruthenium complexes, and various protecting groups such as benzyloxycarbonyl (Cbz) and tert-butyldimethylsilyl (TBS). These chemicals served to build and protect the desired molecular structure during the synthesis process, with the ultimate goal of developing a total synthesis of vancomycin and ristocetin A, which are of clinical importance due to their antibiotic properties and the emergence of resistant bacterial strains.
