  描述：

  (R)-2-(3,4-Dichlorophenyl)-4,4-dimethylpyrrolidine 在 甲醇 、 三乙胺 作用下， 以 乙酸乙酯 、 异丙醇 、 乙腈 为溶剂， 生成 (R)-(3aS,4R,7R,8S,9S,10R,11R,13R,15R,15aR)-10-(((2S,3R,4S,6R)-4-(dimethylamino)-3-hydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-4-ethyl-11-methoxy-3a,7,9,11,13,15-hexamethyl-2,6,14-trioxotetradecahydro-1H-[1]oxacyclotetradecino[4,3-d]oxazol-8-yl 2-(3,4-dichlorophenyl)-4,4-dimethylpyrrolidine-1-carboxylate

  名称：

  Novel 3-O-carbamoyl erythromycin A derivatives (carbamolides) with activity against resistant staphylococcal and streptococcal isolates

  摘要：

  A novel series of 3-O-carbamoyl erythromycin A derived analogs, labeled carbamolides, with activity versus resistant bacterial isolates of staphylococci (including macrolide and oxazolidinone resistant strains) and streptococci are reported. An (R)-2-aryl substituent on a pyrrolidine carbamate appeared to be critical for achieving potency against resistant strains. Crystal structures showed a distinct aromatic interaction between the (R)-2-aryl (3-pyridyl for 4d) substituent on the pyrrolidine and G2484 (G2505, Escherichia coli) of the Deinococcus radiodurans 50S ribosome (3.2 angstrom resolution).
