Oligosaccharide synthesis is hindered by the need for multiple steps as well as numerous selective protections and deprotections. Herein we report a highly efficient de novo route to various oligosaccharide motifs, of use for biological and medicinal

The steric course of the first step of Pd(0)-catalyzed allylic substitution with stabilized C-nucleophiles can be completely reversed by a suitably positioned coordinating Ph2P group, resulting in an overall inversion (1 → 4 → 5), as opposed to t

The reduction has been effected by using a variety of Pd (palladium)-based catalysts. The typical procedure was to suspend 0.25 g of catalyst in 25 cc of an aqueous solution of sodium bicarbonate purged slowly with hydrogen gas. The sodium formate co
