2-aminoethane thiol

D-Xylose has been converted to (25)-3-(indol-3-yl)propane-l,2-diol 237 by two different routes, one involving direct Fischer indolization of 238. The dibenzyl-dithioacetal 239 was elaborated to the fused triazoline 240 following reaction with MCPBA. Initial oxidation was followed by elimination of acetic acid allowing intramolecular 1,3-dipolar cycloaddition reaction to construct the triazole ring. The bicyclic iV,S -acetals 242 and 241 were prepared by reaction of the 2,3-0-isopropylidene-D-ribofuranose with 2-aminoethane thiol followed by Mitsunobu reaction. These products are considered analogues of castanosper-mine and australine. ... [Pg.376]

The dye is initially linked to a ballasted thiazoUdine, which reacts with silver to form a silver iminium complex. The alkaline hydrolysis of that complex yields an alkali-mobile dye. Concomitantiy the silver ion is immobilized by reaction with the ballasted aminoethane thiol formed by cleavage of the thiazolidine ring. [Pg.494]
