Asymmetrische α‐Amidoalkylierung: Synthesen enantiomerenreiner α‐substituierter Piperidine mit 1‐Camphanoyl‐1,2,3,4‐tetrahydropyridin

Abstract: Ph 330[In einer neuartigen. asymmetrischen Synthese wird das homochirale Enamid I diastereoselektiv mit den Silylenolethern 5a-e zu den Amidoalkylierungsprodukte 6/7a-e verknüpft, die für die Gewinnung enantiomerenreiner in a-Stellung R-und S-konfigurierter Piperidinalkohole 9, des Piperidinketons 13, der (R)-Homopipecolinsäure 12R und des Alkaloids (+ )-Sedamin IORR eingesetzt werden.Asymmetrie a-Amidoalkylation.

“…Finally, we ourselves relied on a concept wherein an N-acyl group represents the chiral auxiliary (see 5). The first reagent we developed for this purpose is shown as 5 (Wanner and K~irtner, 1987). In this case the chiral auxiliary can easily be removed and the method as such may readily be applied to the preparation of a whole range of different nitrogen heterocycles.…”
