Synthesis and properties of new 2-mono and 2,3-bis(hydroxymethyl)-6,7-ethylenedithio TTF vinylogs

Autor: Michel Jubault, Catherine Guillot, Piétrick Hudhomme, A. Gorgues, Philippe Blanchard, G. Duguay

Publikováno v: Tetrahedron Letters. 36:1645-1648

The synthesis of title compounds prone to generate hydrogen bonds thanks to their alcohol functionalities is depicted. Cyclic voltammetry proves these derivatives to be strong π-donors, able to act as convenient precursors of related organic metals.

Development of a mathematical model describing the enzymatic degradation of biomedical polyurethanes. 1. Background, rationale and model formulation

Autor: David D. McLean, Daniel G. Duguay, Rosalind S. Labow, J. Paul Santerre

Publikováno v: Polymer Degradation and Stability. 47:229-249

Of the various polymers used in medical devices, polyurethanes have been relatively successful due to their acceptable mechanical and biological properties. However, concerns have arisen in recent years regarding the biostability of polyurethanes whe

Electron ionization mass spectra of hydroxymethyltetrathiafulvalenes and bis(hydroxymethyl)tetrathiafulvalenes

Autor: Philippe Blanchard, Javier Garín, Alain Gorgues, Marc Sallé, G. Duguay, Jesús Orduna

Publikováno v: Rapid Communications in Mass Spectrometry. 8:701-705

The mass spectra of hydroxymethyltetrathiafulvalenes and bis(hydroxymethyl)tetrathiafulvalenes have been studied by electron ionization, metastable analysis and accurate mass measurements. The elimination of water from molecular ions of bis(hydroxyme

α-Methoxy-α-(6H-1,3-thiazin-2-yl)glycinates precursors of 7-methoxycephems by [3+3] cyclocondensation reaction

Autor: Abdelhadi Boussoufi, G. Duguay, Jean-Luc Parrain, Piétrick Hudhomme

Publikováno v: Tetrahedron. 50:12609-12624

We report here a new widely useful and applicable preparation of functionalised 6H-1,3-thiazinic cycloadducts, versatile key intermediates in the total multistep syntheses of 7-methoxycephems (as analogues of 7-methoxycephalosporins).

Control of the enantiomeric purity and correlation with the absolute configuration of N-protected 2-cyanoglycinates

Autor: G. Duguay, Piétrick Hudhomme

Publikováno v: Tetrahedron: Asymmetry. 4:1891-1900

The enantiomeric purity of substituted N-phthaloyl-2-cyanoglycine methyl esters obtained by resolution of covalent diastereoisomers was easily established by measuring the shift separation of signals using Eu(hfc)3. A correlation with the absolute co
