details the development of several suitable noncryogenic metalation conditions for the synthesis of oxazole zincate. Subsequent rounds of high-throughput catalyst screening ultimately led to the identification of several suitable Pd sources that can be used for the Negishi coupling of unsubstituted oxazole. The scope and generality for one of the reported conditions is also presented.

The synthesis of 2-substituted oxazoles is achieved via nickel-catalyzed cross-couplingreaction of 2-methylthio-oxazole and various organozinc reagents. An extension of this method is demonstrated with a chemoselective, one-pot synthesis of unsymmetrical 2,5-disubstitutedoxazoles. This synthesis of 2- and 2,5-substituted oxazoles using this method provides great advantages over previous methods for

(EN) The present invention relates to carbapenem antibacterial agents in which the carbapenem nucleus is substituted at the 2-position with a naphthosultam linked through a CH2 group. The naphthosultam is further substituted with various substituent groups including at least one cationic group. The compounds are represented by formula (I). Pharmaceutical compositions and methods of use are also included.(FR) Agents antibactériens à base de carbapénem dans lesquels le noyau carbapénem est substitué en position 2 par un naphtosultame lié par l'intermédiaire d'un groupe CH2. Le naphtosultame est lui-même substitué par divers groupes de substitution, dont au moins un groupe cationique. Ces composés répondent à la formule (I). Des compositions pharmaceutiques et des procédés d'utilisation sont également décrits.

An improved and scalable procedure to couple ozaxole and thiazole to aryl halides has been demonstrated. The required organozinc reagents were prepared from the aryllithium and solid ZnCl2. These reagents have been successfully coupled to a variety of aryl bromides and aryl iodides in good to excellent yields.
