A new method of anomeric protection and activation based on the conversion of glycosyl azides into glycosyl fluorides.

Carbohydr. Res. 249(1) , 221-41, (1993)

Glycosyl azides provide reliable anomeric protection stable to conditions for hydrolytic removal of ester groups, for reductive opening or release of acetalic diol protection, for the introduction of ...

Highly chemo-, regio-, and enantioselective rhodium-catalyzed cross-cyclotrimerization of two different alkynes with alkenes.

Angew. Chem. Int. Ed. Engl. 53(11) , 2956-9, (2014)

It has been established that a cationic rhodium(I)/(R)-tol-binap complex catalyzes the cross-cyclotrimerization of silylacetylenes, di-tert-butyl acetylenedicarboxylates, and acrylamides with excellen...
