The catalytic asymmetric dihydroxylation of several allyl 2-O-benzyl-Ξ±-D-xylosides with AD-mix Ξ² and PYR(DHQD) 2 shows almost no diastereofacial selectivity if the 3-and 4-OH groups are unprotected or acetylated. Acetal, benzyl ethers and benzoyl esters enhance the diastereoselectivity, in the oppos
