A reagent-controlled SN2-glycosylation for the direct synthesis of β-linked 2-deoxy-sugars.

J. Am. Chem. Soc. , (2014)

The efficient and stereoselective construction of glycosidic linkages remains one of the most formidable challenges in organic chemistry. This is especially true in cases such as β-linked deoxy-sugars, where the outcome of the reaction cannot be controlled us...

Palladium-catalyzed allylic alkenylation of allylic alcohols with n-butyl acrylate.

Chem. Commun. (Camb.) (19) , 2404-5, (2003)

Various allylic alcohols reacted with n-butyl acrylate in the presence of p-toluenesulfonic anhydride and palladium catalysts to yield the corresponding n-butyl 2,5-dienoates with high regioselectivity.
