The reaction between alkylsuccinic anhydrides (III) and O-benzylhydroxylamine yields the acids (VI). These acids (VI) may be coupled with amino-amides (II) by the mixed anhydride procedure, giving a mixture of the racemates (VIII) and (IX). Hydrogenolysis of the O-benzylhydroxamic acids (VIII) and (IX) yields structuralanalogues [(X) and (XI)] of the natural antibioticactinonin (I).

A synthetic route, associated with a high degree of stereoselectivity, has been developed for the synthesis of structuralanalogues (XIII) of actinonin (I). The anhydride–imide method involves the sequence (IIIb)+(V)→[(VI)+(VII)]→(XI)→(XIII). (±)-Amino-amides (IIIb) yielded the (±)-hydroxamic acids with the relative configuration (XIII) and L-amino-amides (X) yielded single enantiomers with the absolute

The present invention relates to novel drug discovery assays which specifically target peptide deformylase containing the typically unstable native catalytic iron metal center. The present invention further relates to methods of identifying compounds which have greater than 10-fold, and preferably greater than 100-fold selectivity for peptide deformylase over other metalloproteases. The invention further provides for compounds having antibacterial activity identified by the assays of the invention, methods of using the compounds to treat bacterial infections and pharmaceutical compositions containing the compounds of the invention.

Nitroalkanes and Dimethyl Maleate as Source of 3-Alkyl Succinic Anhydrides and (E)-3-Alkylidene Succinic Anhydrides
Nitroalkanes react with dimethyl maleate giving a tandem Michaeladdition/elimination of nitrous acid. The obtained (E)-2-alkylidene dimethyl succinates are: (i) reduced to the corresponding 2-alkyl dimethyl succinates which after hydrolysis produce 1,4-dicarboxylic acids that are prone to convert into the corresponding 3-alkyl succinic anhydrides or (ii) hydrolysed to (E)-2-alkylidene-succinic acids that
