ChemInform Abstract: Total Synthesis of (+)-Leukotriene B4 Methyl Ester and Its 5-Epimer from (R)-Glycidol

Autor: Michel Treilhou, I. Frechard‐Ortuno, M. Avignon-Tropis, J. R. Pougny, Gérard Linstrumelle

Publikováno v: ChemInform. 22

The PdCu coupling reaction of a chiral hydroxy-(E,E)-iododiene with a racemic acetylenic alcohol followed by reduction of the dienyne leads to the desired (Z,E,E) geometry and allows synthesis of LTB4 and its 5-epimer after separation of diastereo

Optically active propargylic alcohols from d-xylose useful precursors for LTB4 synthesis

Autor: J. R. Pougny, P. Pianetti, P. Rollin

Publikováno v: Tetrahedron Letters. 27:5853-5856

Using D-Xylose as a source of chirality at C-5 and C-12 in LTB 4 , an efficient synthesis of the optically active propargylic alcohols A and B , chiral precursors for the LTB 4 synthesis, has been achieved.

Chiral Epoxides for Leukotriene Syntheses : A D-Xylose Approach

Autor: J. R. Pougny, P. Rollin

Publikováno v: Journal of Carbohydrate Chemistry. 5:701-704

Characterization of SRS-A, an important mediator of asthma and other hypersensitivity processes, was not achieved until 19791. It has been proposed that leukotriene A4 (LTA4) is the short-lived key...

Synthesis and Serological Properties of Methyl 2,6-Dideoxy-4-O-Me-α-D and L- arabino - hexopyranoside Present in the Glycolipid Phenolic Antigen of Mycobactkrium Kansasii

Publikováno v: Journal of Carbohydrate Chemistry. 7:733-748

Methyl 2,6-dideoxy-4-O-methyl-α-D-arabino-hexopyranoside 13 and its L-enantiomer 14 were synthesized in a 5-step sequence starting from either 6-deoxy-D-glucal or L-rhamnal. The D-enantio-mer was proven to be identical with the non-reducing sugar of
