Reactions of 2,3-O-isopropylidene derivatives of furanosesugars with Grignard reagents afford stereoselectively products with an anti- (erythro-) relationship between the new chiral centre and that at C-2; the corresponding reactions with organolithium reagents are more variable stereochemically, but some predictive guidelines can be established.
