Spectra and Conformation of Some Stereoisomeric 2.3-Disubstituted Morpholines and 5-OxomorpholinesConformational equilibria of cis- and trans-2.3-diphenyl-, 3-methyl-2-phenyl-, and 3.4-dimethyl-2-phenylmorpholines (1-3) and of the related 5-oxomorpholines (4-6) were studied by n.m.r. spectroscopy. It was shown that these compounds assume chair and half-chair conformations, respectively.

    Description / Table of Contents: Carboxonium compounds in Carbohydrate chemistry, XXI. Rearrangement Reactions of 1,6-Anhydro-β-Dgalactopyranose and 1,6-Anhydro-β-Dgulopyranose Triacetates by the Action of Trifluoromethanesulfonic AcidTri-O-acetyl-1,6-anhydro-β-D-galactopyranose (1) affords with trifluoromethanesulfonic acid (TFMS) in a cis-reaction the gulo-ion 3 and in a trans-reaction the talo-ion 4. In addition, the 1,6-anhydrotalofuranose-ion 8 and 1,5-anhydrotalofuranose-ion 9 are obtained as ringcontraction products in considerable amounts. The ring-contraction reactions proceed with retention of configuration. In contrast, the ring transformations between 3-acetoxy-tetrahydropyran (16) and tetrahydrofurfuryl acetate (17) in the presence of TFMS occur with inversion. Tri-O-acetyl-1,6-anhydro-β-D-gulopyranose (27) affords in the presence of TFMS in a cis-reaction predominantly the gulo-ion 3. 1 reacts with TFMS to form the isomerized triacetates 527, 27 and 30 with gulo- and ido-configuration respectively.
    Notes: Tri-O-acetyl-1,6-anhydro-β-D-galactopyranose (1) ergibt mit Trifluormethansulfonsäure (TFMS) in einer cis-Reaktion dasgulo-Ion 3 und in einer trans-Reaktion das talo-Ion 4. Ferner werden in erheblichem Maße als Ringkontraktionsprodukte das 1,6-Anhydrotalo-furanose-Ion 8 und das Anhydrotalofuranose-Ion9 erhalten. Die Ringkontraktions-reaktionen verlaufen stets unter Retention der Konfiguration. Unter Inversion erfolgen dagegen Ringumwandlungen zwischen 3-Acetoxytetrahydropyran (16) und Tetrahydro-furfurylacetat (17) bei Einwirkung von TFMS. Tri-O-acetyl-1,6-anhydro-β-D-gulopyranose (27) liefert bei TFMS-Einwirkung in einercis-Reaktion stark bevorzugt das gulo-Ion 3. Bei der TFMS-Einwirkung auf 1 wurde die Bildung isomerisierter Triacetate der gulo- und ido-Konfiguration 27 und 30 beobachtet.

    Heterocyclen mit Isochinolin-Gerüst aus β-Aminosäuren, 2. Stereospezifische Synthesen von (±)-6.7-Dialkoxy-3-aryl-4-methoxycarbonyl-1.2.3.4-tetrahydro-isochinolinen und ihren Derivaten (1971)

    Description / Table of Contents: Isoquinoline-type Heterocycles from β-Amino Acids, 2. Stereospecific Syntheses of (±)-6.7-Dialkoxy-3-aryl-4-(methoxycarbonyl)-1.2.3.4-tetrahydroisoquinolines and their DerivativesMethyl (±)-3-amino-2.3-diarylpropionates (1) yield under the conditions of the Pictet-Spengler reaction 6.7-dialkoxy-3-aryl-4-(methoxycarbonyl)-1.2.3.4-tetrahydroisoquinolines (2). The cyclization proceeds stereospecifically both in the erythro- and threo-series. Reduction of the trans- and cis-3-aryl-4-(methoxycarbonyl)tetrahydroisoquinolines with lithium aluminium hydride leads to the corresponding 4-hydroxymethyl derivatives (3). According to n. m. r. studies, the 3-aryl-4-(methoxycarbonyl)tetrahydroisoquinolines in deuteriochloroform solution exist in a half-chair conformation with equatorial-pseudoequatorial substituents at C-3 and C-4 for the trans- and pseudoaxial methoxycarbonyl group for the cis-forms. In the trans-4-hydroxymethyl derivatives the substituents at C-3 and C-4 have axial-pseudoaxial orientation, whereas in the cis-compounds the hydroxymethyl group is pseudoaxial. In these cases the preferred conformations are stabilized by intramolecular OH…N bond formation.
    Notes: (±)-3-Amino-2.3-diaryl-propionsäure-methylester (1) liefern unter den Bedingungen der Pictet-Spengler-Reaktion 6.7-Dialkoxy-3-aryl-4-methoxycarbonyl-1.2.3.4-tetrahydro-isochinoline (2). Der Ringschluß vollzieht sich stereospezifisch sowohl in der erythro- als auch in der threo-Reihe. Die trans- und cis-3-Aryl-4-methoxycarbonyl-tetrahydroisochinoline werden mit Lithiumalanat zu den jeweiligen 4-Hydroxymethyl-Derivaten (3) reduziert. Nach den NMR-Spektren besitzen die 3-Aryl-4-methoxycarbonyl-tetrahydroisochinoline in Deuteriochloroform eine Halbsessel-Konformation mit äquatorial-pseudoäquatorialen Substituenten am C-3 und C-4 in der trans- bzw. mit pseudoaxialer Methoxycarbonylgruppe in der cis-Reihe. Bei den trans-4-Hydroxymethyl-Derivaten liegen die gleichen Substituenten axial-pseudoaxial, in der cis-Reihe liegt die Hydroxymethylgruppe pseudoaxial vor. In den beiden letztgenannten Fällen sind die bevorzugten Konformationen durch die innere OH…N-Bindung stabilisiert.
