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 ether-type protection, and for glycosylation processes.

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 excellent chemo-, regio-, and enantioselectivities. Unsymmetrical a... |
