    Notes: Bei der Reaktion von 2-Amino-thiophenol (1) mit 1.2-Dicarbonylverbindungen 2 entstehen 2.2′-Bibenzothiazolinyle 4 oder Tetrahydro-benzotlhiazino-benzothiazine 14, die sich in alkalischem Medium zu den Dianionen 3a der offenkettigen Schiffschen Basen 3 umlagern und mit Übergangsmetall-Ionen der zweiten Nebengruppe des Periodensystems tieffarbige 1.2-Dicarbonyl-bis-[2-mercapto-anil]-Chelate 5 bilden. Analoges Verhalten zeigen die Kondensationsprodukte aus 2-Amino-thiophenol und 1.3-sowie 1.4-Dialdehyden, deren Komplexbildung untersucht wird.

    Description / Table of Contents: Influences of Configuration, Conformation, and Subtituents on the 13C Chemical Shifts in Glycosides 6. Mitteil. über Fourier-Transform-13C-NMR-Spektroskopie: 5. Mitteil.: W. Voelter, G. Jung, E. Breitmaier und E. Bayer, Z. Naturforsch. 1971, im Druck.The pulse Fourier transform 13C n.m.r. spectra of 20 methyl and aryl glycosides are discussed. Configurational and conformational assignments can be made using the 13C chemical shifts of these compounds. Anomeric glycosides can be easily distinguished following this method.
    Notes: Die Impuls-Fourier-Transform-13C-NMR-Spektren von 20 Methyl- und Arylglykosiden werden diskutiert. Ihre Konfiguration und Konformation kann aus den 13C-chemischen Verschiebungen zugeordnet werden. Auch anomere Glykoside lassen sich auf diese Weise leicht unterscheiden.

    Description / Table of Contents: Convenient Synthesis of 2-Amino-ω-(uracil-1-yl and thymin-1-yl)-n-alkanoic AcidsA convenient synthesis of α-amino acids with uracil-1-yl (10,11) and thymin-l-yl (12-14) residues in the side chain is described. These amino acids were available only by multistep syntheses as yet. The reaction of 2,4-bis-O-(trimethylsilyl)uracil (1) and -thymin (2) and an α-ω-dibromalkane yields N1- (ω-bromoalkyl)uracil (3-5) and -thymine (6-8). 4-8 are reacted with the sodium salt of N, N-bis (trimethylsilyl)glycine trimethylsilyl ester (9) yielding 2-amino-ω-(uracil-1-yl and thymin-l-yl)-n-alkanoic acids (10-14).
    Notes: Für die bislang nur schwierig über mehrstufige Synthesen zugänglichen α-Aminosäuren mit Uracil-1-yl- (10, 11) und Thymin-1-yl-Rest (12-14) in der Seitenkette wird eine einfache Darstellungsmethode beschrieben. Durch Reaktion von 2,4-Bis-O-(trimethylsilyl)uracil (1) bzw.  - thymin (2) mit einem α,ω-Dibromalkan erhält man N1-(ω-Bromalkyl)uracil (3-5) bzw.  - thymin (6-8). 4-8 werden mit dem Natriumsalz von N,N-Bis(trimethylsilyl)glycin-trimethylsilylester (9) zu den 2-Amino-ω-(uracil-l-yl bzw. thymin-l-yl)-n-alkanäuren (10-14) umgesetzt.

    Description / Table of Contents: Monoterpenoid Glucosides from the Leaves of Betula alba and the Fruits of Chaenomeles japonicaTwo stereoisomeric monoterpenoid glycosides, betulalbuside A and B (3a and 4a), were isolated from the leaves of Betula alba (Betulaceae) and from the fruits of Chaenomeles japonica (Rosaceae). By spectroscopic methods their constitutions were shown to be 9-hydroxylinalool 9- and 1-hydroxylinalool 1-β-D-glucopyranoside, respectively.
    Notes: Aus Birkenblättern, Betula alba (Betulaceae), und den Früchten von Chaenomeles japonica (Rosaceae) wurden zwei stereoisomere Monoterpen-Glycoside Betulalbusid A und B (3a und 4a) isoliert. Ihre Konstitutionen konnten vorwiegend spektroskopisch als 9-Hydroxylinalool-9- bzw. 1-Hydroxylinalool-1-β-D-glucopyranosid ermittelt werden.

    Notes: 3-Alkylquinolizinium Iodides from Metalated α-Picoline and 3-Ethoxyacroleins2-Alkylquinolizinium iodides 4 are obtained in good overall yields by treating lithiated 2-methylpyridine 1 with 2-alkyl-3-ethoxyacroleins 2. 3-Alkyl-4-ethoxy-1-(2-pyridyl)-3-buten-2-ols 3 are isolated as primary products which readily cyclize to give the title compounds 4 upon heating in aqueous hydrogen iodide.

    Description / Table of Contents: Synthesis of Cycloalkeno[b]pyridines from 2-(Aminomethylene)cycloalkanones and 1,3-Dicarbonyl Compounds2-(Aminomethylene)cycloalkanones react with 1,3-dicarbonyl compounds to give the cycloalkeno[b]pyridines 4-7, the 1H and 13C n.m.r. spectra of which are discussed. The chemical shift values of the heteroaromatic bridge-head carbon atoms are found to alternate on variation of the fused cycloaliphatic ring.
