摘要：

Peracetylated 2-deoxy-D-erythro-pentose (2-deoxy-D-ribose) was synthesized through the acetylation of 2-deoxy-D-ribose with acetic anhydride in pyridine, and the products (including all four ring forms) exist in form of either a white solid or a syrup. A single crystal of 1,3,4-tri-O-acetyl-2-deoxy-beta-D-erythro-pentopyranose was obtained from the syrup and its structure was determined by X-ray diffraction. The crystal adopts the C-1(4) conformation, presenting an orthorhombic system, space group P2(1)2(1)2(1) with Z=4, unit cell dimensions a=7.2274 (3)angstrom, b=8.0938 (5) angstrom, and c=22.0517 (11) angstrom.
