Process for 6-(aminomethyl)penicillanic acid 1,1-dioxide and derivatives thereof

A process for the preparation of beta-lactamase inhibiting 6-alpha-(aminomethyl)penicillanic acid 1,1-dioxide and derivatives. R- and S-1-(ethoxycarbonyloxy)ethyl 6-alpha-(aminomethyl)penicillanate 1,1-dioxide are specifically described.

6-(Aminomethyl)penicillanic acid 1,1-dioxide esters and intermediates therefor

6-alpha- and 6-beta-(Aminomethyl)penicillanic acid, 1,1-dioxide esters which are hydrolyzable under physiological conditions, particularly those wherein the ester radical is 1H-isobenzofuran-3-on-1-yl or (5-methyl-1,3-dioxol-2-on-4-yl)methyl, and an improved process and intermediates used in their synthesis.

Salts of 6-alpha-(aminomethyl)penicillanic acid 1,1-dioxide esters and beta-lactam antibiotics

Salts of readily hydrolyzable esters of 6-alpha-(aminomethyl)penicillanic acid 1,1-dioxide and (a) prodrug forms of ampicillin and amoxicillin or (b) ampicillin and amoxicillin and a dibasic acid are readily absorbed following oral adminstration, and are

6-Aminomethylpenicillanic acid 1,1-dioxide derivatives as beta-lactamase inhibitors

beta-Lactamase inhibitors which are 6-alpha- and 6-beta(aminomethyl)pencillanic acid 1,1-dioxides which are substituted on amino nitrogen with benzyl, hydroxybenzyl, picolyl or phenethyl; pharmaceutically-acceptable salts thereof; conventional esters ther

6-Aminoalkylpenicillanic acid 1,1-dioxides as beta-lactamase inhibitors

Beta-lactamase inhibitors which are 6-alpha- and 6-beta-(aminomethyl) and (1-aminoethyl)pencillanic acid 1,1-dioxides; pharmaceutically-acceptable salts thereof; conventional esters thereof which are hydrolyzable in vivo; bis-methanediol esters thereof; o

1,1-Alkanediol dicarboxylate linked antibacterial agents

Useful antibacterial agents in which a penicillin and/or a beta-lactamase inhibitor are linked via 1,1-alkanediol dicarboxylates are of the formula STR1 where A is the residue of certain dicarboxyic acids, R3 is H or (C1 -C3), n is zero or 1 such that when n is zero R is P or B and R1 is the residue of certain esters, H or a salt thereof; and when n is 1, one of R and R1 is P and the other is B, and P is STR2 where R2 is H or certain acyl groups, and B is the residue of a beta-lactamase inhibiting carboxylic acid; a method for their use, pharmaceutical compositions thereof and intermediates useful in their production.

Bis-esters of dicarboxylic acids with amoxicillin and certain hydroxymethylpenicillanate 1,1-dioxides

Antibacterial bis-esters of 1,4-cyclohexanedicarboxylic acids and alkane dicarboxylic acids wherein the ester moieties are derived from different alcohols; one alcohol being hydroxymethylpenicillanate 1,1-dioxide, or the 6-beta-hydroxymethyl or the 6-alpha-aminomethyl derivative thereof; and the other being 6-[D-(2-amino-2-(p-hydroxyphenyl)acetamido)]penicillanic acid (amoxicillin); and pharmaceutically acceptable salts thereof; a method for the use of said esters and their salts, and methods for their preparation.
