Thio Sugars: Stereochemical Questions and Synthesis of Antimetabolites

Dithioacetals of sugars provide useful starting materials for synthesis of various deoxy sugar derivatives by way of polythio intermediates, and also afford convenient access to acyclic aldose derivatives having two different substituents at C-i. The conformations of aldose diethyl and diphenyl dithioacetals in solution, as determined by p.m.r. spectroscopy with the aid of lanthanide salts, fol...

Utilization and Addition Sugars to Ruminants Rations

Responses to sugars in dry or liquid formvary from study to study. When fed in proper amounts, sugars should not depress ruminalpH, and there is some evidence that they actuallyhelp toprevent a drop in pH after consuming largemeals of concentrate by maintaining a highernumberoflactate-fermenting bacteria. Adding sugars doesprioritize the need for rumen degraded protein (RDP).we all know, sugars...

Regioselective (thio)carbamoylation of 2,7-di-tert-butylpyrene at the 1-position with iso(thio)cyanates

It has been found that 2,7-di-tert-butylpyrene reacts with aliphatic iso(thio)cyanates in the presence of trifluoromethanesulfonic acid to exclusively afford the corresponding 1-substituted (thio)amides in high yields. For aromatic iso(thio)cyanates the reaction is less regioselective, although substitution at the 1-position prevails. For ethoxycarbonyl isothiocyanate, apart from the 1-substitu...

A facile and general route to 3-((trifluoromethyl)thio)benzofurans and 3-((trifluoromethyl)thio)benzothiophenes.

A facile and general route to 3-((trifluoromethyl)thio)benzofurans and 3-((trifluoromethyl)thio)benzothiophenes is reported. The reactions of trifluoromethanesulfanylamide with 1-methoxy-2-alkynylbenzenes or methyl(2-alkynylphenyl)sulfanes promoted by BiCl3 proceed smoothly with broad functional group tolerance.

Urinary Sugars—A Biomarker of Total Sugars Intake

Measurement error in self-reported sugars intake may explain the lack of consistency in the epidemiologic evidence on the association between sugars and disease risk. This review describes the development and applications of a biomarker of sugars intake, informs its future use and recommends directions for future research. Recently, 24 h urinary sucrose and fructose were suggested as a predicti...
