Zur Reaktion von 2,4‐Dioxo‐3‐azabicyclo(3,3,1)nonan mit metallorganischen Reagenzien, 2. Mitt. Zyklisierung und Reduktion von 3‐(Diphenyl‐hydroxymethyl)‐cyclohexancarbonsäure‐N‐methylamid

Abstract: Der Versuch, das durch Grignardierung eines Bicyclo-(3,3,l>nonanderivats entstandene 6-Hydroxyamid 1 unter Wasserabspaltung zu zyklisieren, fuhrt zum Olefinamid 2 bzw. zum Lacton 3. Das korrespondierende Lactam wird nieht erhalten. Lithiumalanatreduktion des zu 1 fuhrenden Grignardkomplexes vor der Hydrolyse ergibt das Amin 7. Ausgehend von 7 wird iiber 10, das als Produkt einer anomal verlaufenden Lackurf-Wdluch-Reaktion erhalten wird, das Bicyclo(4,3,l)decan 12 synthetisiert.The Reaction of 2,4-Diox~3-azabic… Show more

“…Dibenzyl ketone has also been used to a larger extent as the ketone component in the Mannich reaction. In this way l,5-diaryl- In the reaction of dibenzyl ketone, paraformaldehyde, and ammonium acetate l,5-diphenyl-3-hydroxymethyl-9-ethoxy-9-hydroxy-3,7-DABN acetate (77) is Dibenzyl ketone after nitration also undergoes Mannich reaction to give the corresponding 3,7-DABNs.110 On introduction of methyl substituents in the ortho positions of the phenyl groups of dibenzyl ketone the ease of formation of 3,7-DABN decreases. Bispidines are formed from l-phenyl-3-(o-tolyl)-propan-2-one almost as easily as from l,3-diphenylpropan-2-one.…”
