Stereoselective palladium catalyzed cyclization on carbohydrate templates - A route to chiral cyclopentanes and some heterocyclic analogs

Certain pseudoglycals are shown to be excellent substrates for the palladium catalyzed introduction of unsaturated pendants into the 1-, 2- or 4-positions followed by Pd-mediated cyclization. This methodology provides a ready entry into homochiral substit
