Cycloadditions - Carbohydrates: Tools for Stereoselective Synthesis - page 101

d-xylofuranose 235b and d-galactopyranose 235c gave virtually no diastereoselec-
tivity. The best result was achieved using 1,2-deoxy d-glucose derivative 235d,
which offered up to 80% de. This study highlights, once again, how strong an
impact the carbohydrate architecture may have on stereoselectivity.
