DOCUMENT TYPE: Journal CA Section: 32 (Steroids) Section cross-reference(s): 23, 33 The reaction of xanthates, thiobenzoates, thiocarbamates, and selenobenzoates with soft electrophilic reagents provides a simple, mild, and high-yield method of OH replacement. S-Me O-stearyl dithiocarbonate treated with a range of halide derivs. in CH2Cl2 gave 50-100% of the corresponding stearyl halide. Treatment of O-cholest-5-en-3.beta.-yl S-Me dithiocarbonate or O-cholest-5-en-3.beta.-yl thiobenzoate with PhSCl gave 3.beta.In this experiment, several chemicals are used like 62008-68-8 and 4064-06-6 -chlorocholest-5-ene. The galactoses I (R = Cl, Br, I) were prepd. from the galactose I (R = OCS2Me) with PhSCl, Br, and MeI, resp. .

DOCUMENT TYPE: Journal CA Section: 33 (Carbohydrates) Benzenesulfinyl morpholine (BSM) was applied as a new promoter for the activation of thioglycosides. Di-, tri-, and tetrasaccharides were prepd. via stereoselective glycosylation from thioglycosides which were in situ activated by BSM and trifluoromethanesulfonic anhydride. This strategy works well for one-pot oligosaccharide assembly. .
