  The first total synthesis of telephiose A

  摘要：

  The first total synthesis of telephiose A (1), a novel trisaccharide ester having two acetyl groups and two benzoyl groups, was achieved by using glucosyl donor 6 and disaccharide acceptor 12. The crucial key step was the stereoselective construction of the beta-D-glucosidic linkage featuring the neighboring group participation of the 2-O-N-phenylcarbamoyl group (of donor 6), which can be selectively deprotected in the presence of acetyl and benzoyl groups. Donor 6 was prepared from D-glucose in eight steps (33% yield), whereas acceptor 12 was prepared from sucrose in six steps (35% yield). Precursors 6 and 12 were reacted in subsequent reactions (five steps) to afford 1 in 22% yield. (c) 2007 Elsevier Ltd. All rights reserved.
