obtained by Ti(IV)-mediated cyclopropanation of amino acid derivatives, constitute versatile, and unprecedented intermediates for the asymmetric synthesis of pharmacologically active products. Indeed, through selective rearrangement, these compounds undergo unusual ring cleavage to lead to pyrrolidinones. Fe(III)-promoted ring opening followed by basic dehydrohalogenation furnishes opticallyactive dihydropyridinones

furnish racemic pyrrolidinones as a mixture of diastereomers and piperidinones. In contrast, the synthesis of optically active dihydropyridinones was achieved through a one-pot FeCl3/AcONa reaction or performed by using bis(sym-collidine)iodine hexafluorophosphate. Furthermore, whereas the palladium-mediated hydrogenolysis of these dihydropyridinones furnished both chiral piperidinones and original pyridinols

Starting from readily available dihydropyridinones, we have developed the first synthesis of (S)-2-phenylpiperidin-3-one. While the scaffold appears relatively common, even in its racemic form, this original product can be considered as a potential precursor of substance P antagonist.
从容易获得的二氢吡啶酮开始,我们首次合成了(S)-2-苯基哌啶-3-酮。虽然这种支架看起来比较常见,甚至是外消旋形式,但这种原始产物可被视为 P 物质拮抗剂的潜在前体。
