General and Chemoselective N-transacylation of secondary amides by means of perfluorinated anhydrides

A direct route: The N-transacylation of secondary amides to their perfluorinated analogues with the possibility of subsequent conversion into a normal amide is reported (see scheme). This reaction occurs in the presence of a variety of functional groups that are labile to the hydrolysis conditions required by classical N-transacylation. Chemical equation representation

Tandem one-pot acetalation-acetylation for direct access to differentially protected thioglycosides and O-glycosides with p-toluenesulfonic acid

A new tandem one-pot acetalation-acetylation procedure is reported which streamlines routine protecting-group manipulation of carbohydrate molecules in production of differentially protected O- and thioglycosides. This new procedure eliminates the use of
