X-Ray diffractometry of methyl 3,4-anhydro-a-nL-allopyranoside (3) revealed the crystals to be monoclinic, space group Cc, with cell dimensions a = 6242(l), b = 16.987(2), c = 7.739(l) A; /I = 106.09(l)", Z = 4. The 3,4\_anhydropyranose ring adopts a hybrid 'E + '&conformation. Relatively strong int
