| Abstrakt: | Single crystals of benzyl 3,4-anhydro-2-O-mesyl-6-O-trityl-α-d-altropyranoside (1) were tetragonal, space group P41, with cell dimensions a= 16.393(3), b= 16.393(2), c= 11.952(2) Å, Z= 4. The 3,4-anhydropyranose ring adopts a half-chair (1Ho) conformation. The conformations of 3,4-anhydro-α-d-hexopyranosides with the allo, altro, galacto, and taloconfigurations are discussed. |
