Total synthesis of bottromycin A2 can be accomplished through a diastereoselective Mannich reaction of a chiral sulfinamide, mercury-mediated intermol. amidination, and cyclization of a constrained tetracyclic peptide. Exploitation of this process allowed the synthesis of several novel bottromycin analogs. The antimicrobial activity of these analogs was evaluated in vitro against Gram-pos. bacteria, such as methicillin resistant Staphylococcus aureus (MRSA) and vancomycin resistant enterococci (VRE). Structure-activity relationships were explored taking into consideration the unique three-dimensional structure of the compounds Notably, one of the new analogs devoid of a Me ester, which is known to lower the in vivo efficacy of bottromycin, exhibited antibacterial bioactivity comparable to that of vancomycin. In the experiment, the researchers used many compounds, for example, Thiazol-2-ylmethanamine (cas: 55661-33-1Application of 55661-33-1).
Thiazol-2-ylmethanamine (cas: 55661-33-1) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current. Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Application of 55661-33-1
