Pyrrole C-glycosylated in either the 2-or the 3-position could be prepared by the acid-catalyzed reaction between trichloroacetimidate glycosyl donors and pyrrole, or N-phenyl-tri?uoroacetimidate glucosyl donor and N-TIPS pyrrole, respectively. Pyrroles c

Inexpensive 3-(dimethylamino)-1-propylamine (DMAPA) was found to be effective in anomeric deacylation reactions giving 1-O deprotected sugars in high yield as precursors for the formation of imidate glycosyl donors. DMAPA was also found to be useful for removing excess reagents such as benzoyl chloride, tosyl chloride, and 2,2,2-trifluoro-N-phenylacetimidoyl chloride. The deacylation reaction could be conducted in moist THF and did not require chromatographic purification since an acidic wash was sufficient to remove excess reagent and the formed byproduct.

(Chemical Equation Presented) The first O-glycosylation of hydroxamic acids is reported. This process involves the use of glycosyl N-phenyl trifluoroacetimidates as glycosyl donors in the presence TMSOTf and 4 A molecular sieves in dichloromethane. Under
