copper-catalyzed allylation of ketones using widely available 1,3-dienes as allylmetal surrogates. Homoallylic alcohols bearing a wide range of functional groups are obtained in high yield and with good regio-, diastereo-, and enantioselectivity. Mechanistic investigations using density functional theory (DFT) implicate the in situ formation of a rapidly equilibrating mixture of isomeric copper(I) allyl complexes

Zur absoluten Konfiguration der Enantiomere der Antimuskarinika Procyclidin und Tricyclamoliodid: Röntgen-strukturanalyse von (R)-1-[3-Cyclohexyl-3-hydroxy-3-phenyl-propyl]-1-methylpyrrolidiniumiodid
Durch Röntgenstrukturanalyse von (R)-1-[3-Cyclohexyl-3-hydroxy-3-phenylpropyl]-1-methyl-pyrrolidiniumiodid [(R)-Tricyclamoliodid, (R)-2a] wurden die absoluten Konfigurationen der Enantiomere der Antimuskarinika Procyclidin (1a) und Tricyclamoliodid (2a) bestimmt. (R)-1a und (R)-2a sind etwa 380-bzw. 90mal stärker antimuskarinisch wirksam (isoliertes Meerschweinchen-Ileum) als die entsprechenden (S)-konfigurierten
