Synthesis and structure-activity relationships of 3-thiazoliomethyl derivatives》 was written by Nakayama, Eiji; Fujimoto, Koichi; Muramatsu, Shigeki; Miyauchi, Masao; Watanabe, Katsuhiko; Ide, Junya. Safety of (6R,7R)-Benzhydryl 7-amino-3-(chloromethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate hydrochloride And the article was included in Journal of Antibiotics on August 31 ,1991. The article conveys some information:
The synthesis and structure-activity relationships of the title compounds, e.g., I (R = H, Me, CH2CH2F; X = O, S) are described. Of all the thiazoliomethyl derivatives prepared the most potent bactericides were I. In addition to this study using (6R,7R)-Benzhydryl 7-amino-3-(chloromethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate hydrochloride, there are many other studies that have used (6R,7R)-Benzhydryl 7-amino-3-(chloromethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate hydrochloride(cas: 79349-53-4Safety of (6R,7R)-Benzhydryl 7-amino-3-(chloromethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate hydrochloride) was used in this study.
(6R,7R)-Benzhydryl 7-amino-3-(chloromethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate hydrochloride(cas:79349-53-4) is one of azetidine.Azetidines (azacyclobutanes) constitute a well-known class of heterocyclic compounds. Azetidine scaffold has been discovered in several natural products.Safety of (6R,7R)-Benzhydryl 7-amino-3-(chloromethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate hydrochloride Several pharmacologically important synthetic compounds also contain azetidine ring. Because of inherent ring strain, the synthesis of azetidines is a challenging endeavor.
