概要 The first total synthesis of telephiose A, a novel trisaccharide ester having two acetyl groups and two benzoyl groups, was achieved by using glucosyl donor I and sucrose deriv. acceptor. The crucial key step was the stereoselective construction of the -D-glucosidic linkage featuring the neighboring group participation of the 2-O-N-phenylcarbamoyl group of donor I, which can be selectively deprotected in the presence of acetyl and benzoyl groups. Donor I was prepd. from D-glucose in eight steps (33% yield), whereas acceptor sucrose deriv. was prepd. from sucrose in six steps (35% yield). ...
