Phosphine-Catalyzed [4+2] Cycloadditions of Allenic Ketones: Enantioselective Synthesis of Functionalized Tetrahydropyridines
Amino-acid-derived phosphine catalyzed [4+2] cycloaddition leading to chiral tetrahydropyridines, making use of alpha-substituted allenic ketones as C4 synthons and N-sulfonyl cyclic ketimines, has been developed. This asymmetric cycloaddition tolerates a wide range of alpha-substituted allenic ketones. A series of chiral sultam-fused tetrahydropyridines bearing a quaternary stereocenter were obtained in high yields with good enantioselectivities.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 51805-45-9, you can contact me at any time and look forward to more communication. COA of Formula: C9H16ClO6P.
