A safe and convenient method for the copper(II)-catalyzed diazotransfer from triflyl azide to primary amines is reported. By replacing CH2Cl2 by toluene the formation of hazardous side products, for example, azido-chloromethane and diazidomethane can be avoided.

Hydroxy carboxy pyrrolyl-indolinone derivatives have enhanced and unexpected drug properties as inhibitors of protein kinases and are useful in treating disorders related to abnormal protein kinase activities such as cancer. More particularly, alpha-hydroxy-omega-(2-oxo-indolylidenemethyl-pyrrole-3′-carbonyl) amino alkanoic acid and amide derivatives have enhanced and unexpected drug properties as inhibitors of protein kinases with respect to their corresponding beta-hydroxy-omega-(2-oxo-indolylidenemethyl-pyrrole-3′-carbonyl) amino alkanoic acid and amide derivatives and are useful in treating disorders related to abnormal protein kinase activities such as cancer.

Cefiderocol (S-649266), A new siderophore cephalosporin exhibiting potent activities against Pseudomonas aeruginosa and other gram-negative pathogens including multi-drug resistant bacteria: Structure activity relationship
The structure-activity relationship (SAR) for a novel series of catechol conjugated siderophore cephalosporins is described with their in vitro activities against multi-drug resistant Gram-negative pathogens including Pseudomonas aeruginosa, Acinetobacter baumannii, Stenotrophomonas maltophilia and Enterobacteriaceae. Cefiderocol (3) was one of the best molecules which displayed well-balanced and potent activities against multi-drug resistant Gram-negative pathogens including carbapenem resistant bacteria among the prepared compounds with the modified C-7 side chain and the modified C-3 side chain. Cefiderocol (3) is a highly promising parenteral cephalosporin for the treatment of multi-drug resistant Gram-negative infection. (C) 2018 Elsevier Masson SAS. All rights reserved.
