    <p>Azabicyclo[3.1.1]heptanes are recognized as bioisosteres of the meta-substituted pyridine scaffold, as their bridgehead substitution mimics the arrangement of substituents on the meta-substituted pyridine. However, the synthesis of azabicyclo[3.1.1]heptanes remains underdeveloped. This mini-review highlights recent advances in their synthesis through strain-release cycloadditions of bicyclo[1.1.0]butanes.</p>

  • Aerobic Photoredox Catalyzed Oxamate Ester Synthesis from Bromodifluoroacetate Esters Reviewed International journal

    Here we report an aerobic photoredox catalysis approach to oxamate ester synthesis using bromodifluoroacetate esters and amines under open-air conditions. Oxamate ester is an important skeleton found in bioactive molecules and used as a synthetic building block. However, previous synthetic methods require the use of moisture- and air-sensitive precursors and/or harsh conditions, limiting accessible oxamate esters. The present method uses bench-stable bromodifluoroacetate esters and amines under mild photoredox catalytic conditions to furnish a wide variety of oxamate esters. Combining photoredox catalysis with aerobic oxygenation enables the use of bromodifluoroacetate ester as a precursor for the synthesis of oxamate esters via fluoroglyoxylate esters.
