4-dichlorophenyl)-D-xylo-hex-5-enit ol and 2-C-[(R)-acetoxy(2,4-dichlorophenyl)methyl]-3,4,6-tri-O-acetyl-2-deoxy- beta-L-galacto- and -beta-L-gulo-hexopyranosylbenzene. The mechanism of this new rearrangement was studied by exchanging the substituents at C-1 and C-3 in 3 and those of the aromatic ring attached to C-6.
