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。

Starting from 2-carboxy-3-thenylazide and enantiopure amines as the chiral building blocks, we developed a two-step synthesis of the title compounds involving an intramolecular azide cycloaddition as the key step.
