STEREOCONTROLLED SYNTHESIS OF HIGHLY FUNCTIONALIZED CYCLOHEXENES. A SHORT SYNTHESIS OF A CHORISMIC ACID PRECURSOR

A convenient and mild thermal procedure has been developed for stereoselective 2+4-cycloadditions of electron-rich 1,2-dioxygenated olefins 7 to electron-deficient 3-sulfonyl-2-pyrone 6 allowing isolation of the structurally and stereochemically rich init

Highly Stereocontrolled Synthesis of Some Polyfunctionalized Cyclohexenes. A Short Formal Total Synthesis of (+/-)-Chorismic Acid

Lewis acid catalysis or high pressure is an effective means for promoting stereocontrolled 2 + 4 cycloaddition between pyrone sulfoxide 1 and vinyl ethers and vinyl thioethers.The bridged, bicyclic lactone cycloadducts are versatile synthons carrying much
