A simple azabicyclic peroxide synthesis was achieved by the manganese(III)-mediated oxidative formal [2+2+2] cycloaddition. A mixture of tetramic acid derivatives and alkenes was oxidized with manganese(III) acetate under a dry air stream to give 1-hydroxy-8-aza-2,3-dioxabicyclo[4.3.0]nonan-7-ones in good to quantitative chemical yields.
The present invention relates to compounds that are selective and/or potent inhibitors of UPPS. In addition to compounds which inhibit UPPS, the invention also provides pharmaceutical compositions comprising these compounds and methods of using these compounds for treating bacterial disease, such as bacterial infection.
Design and structure–activity relationships of potent and selective inhibitors of undecaprenyl pyrophosphate synthase (UPPS): Tetramic, tetronic acids and dihydropyridin-2-ones
Based on a pharmacophore hypothesis substituted tetramic and tetronic acid 3-carboxamides as well as dihydropyridin-2-one- 3-carboxamides were investigated as inhibitors of undecaprenyl pyrophosphate synthase (UPPS) for use as novel antimicrobial agents. Synthesis and structure - activity relationship patterns for this class of compounds are discussed. Selectivity data and antibacterial activities for selected compounds are provided.

We have synthesized and evaluated a series of tetramic acid-based and hydroxvquinolinone-based inhibitors of plasminogen activator inhibitor-1 (PAI-1). These studies resulted in the identification of several compounds which showed excellent potency against PAI-1. The design, synthesis and SAR of these compounds are described.
