[Reaction: see text]. A collection of 13 unsymmetrical ketones, each one featuring a sugar (d-glucosyl, d-galactosyl, d-mannosyl, and l-fucosyl) and an aglycone moiety (phenyl, 2-thiazolyl, TMS-ethynyl, allyl, and 1-propenyl) was prepared by a uniform route based on the use of benzothiazole as a carbonyl group equivalent. Succinctly,(More)
Isolated in 1995, the four members of the louisianin family (A, B, C and D) are simple pyridine and 2-pyridone alkaloids that display both antibacterial and anticancer activity. Herein we describe the synthesis of all four members of the louisianin family, from a conveniently prepared 1,2,4-triazine and via a common tetrasubstituted pyridine intermediate.(More)
An efficient synthesis of O-benzylated derivatives of the title sugar aldehydes via thiazole addition to tri-O-benzyl-l-fuconolactone followed by highly stereoselective deoxygenation of the resulting thiazolylketose and thiazole to formyl transformation is described. Wittig olefination of these aldehydes with galactopyranose and glucopyranose 6-phosphoranes(More)
