generates the most effective molybdenum catalysts known to date. The reactive catalyst proved to be Mo(RNC) 4 (CO) 2 . With this new catalyst, a much broader range of substrates can be employed including many that failed or reacted very poorly by using molybdenumhexacarbonyl. The regioselectivity also differs from that obtained with molybdenumhexacarbonyl. The stereochemistry of the reaction proceeds with
The invention relates to antibacterial compounds of formula (I) wherein M is one of the groups MA, MB and MC represented below wherein R1, MA, MB and MC are as defined in the specification; and to salts thereof.
LpxC inhibitors were optimized starting from lead compounds with limited efficacy and solubility and with the goal to provide new options for the treatment of serious infections caused by Gram-negative pathogens in hospital settings. To enable the development of an aqueous formulation for intravenous administration of the drug at high dose, improvements in both solubility and antibacterial activity
