BETA-LACTAMASE INHIBITOR COMPOUNDS

The present invention is directed to compounds which are beta-lactamase inhibitors. The compounds and their pharmaceutically acceptable salts are useful in combination with beta- lactam antibiotics, for the treatment of bacterial infections, including infections caused by drug resistant organisms, including multi-drug resistant organisms. The present invention includes compounds according to Formula (I): or a pharmaceutically acceptable salt thereof, wherein the values of R1, R2, R3, R4, R5 and R6 are described herein.

Total synthesis of (-)-martinellic acid

An enantioselective formal total synthesis of the pyrrolo[3,2-c]quinoline natural product martinellic acid has been achieved. The key steps involve a Pd-catalyzed aryl amidation reaction of a pyrroglutamate derivative, an intramolecular [3+2] azomethine ylide-alkene cycloaddition and a reductive ring opening reaction.

Total synthesis of (+)-batzelladine A and (-)-batzelladine D via [4 + 2]-annulation of vinyl carbodiimides with N-alkyl imines

A diastereoselective [4 + 2]-annulation of vinyl carbodiimides with chiral N-alkyl imines has been developed to access the stereochemically rich polycyclic guanidine cores of the batzelladine alkaloids. Application of this strategy, together with additional key steps such as long-range directed hydrogenation and diastereoselective intramolecular iodo-amination, led to highly convergent total syntheses of (-)-batzelladine D and (+)-batzelladine A with excellent stereocontrol.

The synthesis of di(hydroxyalkyl) substituted bicyclic guanidines

The synthesis of the enantiomerically pure bicyclic guanidines 3a and 3b is described.The convergent strategy is based on methodology developed by Schmidtchen.The therefore required amine components 6 and 9 obtained from methionine and L-glutamic acid, respectively.

Synthesis of a Chiral Di(hydroxyalkyl) Substituted Bicyclic Guanidine

Schmidtchen's methodology is used successfully for the synthesis of the chiral disubstituted bicyclic guanidinium salt 2.The two therefore required primary amine compounds 6 and 9 are obtained from L-methionine and L-glutamic acid, respectively.

Process for preparing 5-vinyl-2-pyrrolidinone and intermediates therefor

4-Amino-5-hexenoic acid is prepared by: (a) reacting 5-oxo-2-pyrrolidine-acetonitrile with hydrogen and dimethylamine in the presence of a palladium catalyst to form N,N-dimethyl-2-[5'-oxo-2'-pyrrolidine]ethylamine; (b) oxidizing N,N-dimethyl-2-[5'-oxo-2'-pyrrolidine]-ethylamine to produce the corresponding N-oxide derivative; (c) pyrolysis of the N-oxide derivative to form 5-vinyl-2-pyrrolidinone; (d) optionally, separating N,N-dimethyl-2-[5'-oxo-2'-pyrrolidine]ethylamine by-product from the 5-vinyl-2-pyrrolidinone product; and (e) hydrolyzing 5-vinyl-2-pyrrolidinone to form 4-amino-5-hexenoic acid.
