  • O-Isopropylidenation of carbohydrates catalyzed by vanadyl triflate
    作者:Chun-Cheng Lin、Mi-Dan Jan、Shiue-Shien Weng、Chang-Ching Lin、Chien-Tien Chen
    DOI:10.1016/j.carres.2006.04.001
    日期:2006.8
    Vanadyl triflate has been identified as a mild and efficient catalyst for the chemoselective O-isopropylidenation of functionalized carbohydrates with acetone and acetone equivalents. The current protocol is compatible with a diverse array of protecting groups and the products can be readily isolated by simple aqueous wash. (c) 2006 Elsevier Ltd. All rights reserved.
  • Syntheses of a series of lacto-N-neotetraose clusters using a carbosilane dendrimer scaffold
    作者:Akihiro Yamada、Ken Hatano、Tetsuo Koyama、Koji Matsuoka、Yasuaki Esumi、Daiyo Terunuma
    DOI:10.1016/j.carres.2005.11.037
    日期:2006.3
    4-Pentenyl (2,3,4,6-tetra-O-acetyl-beta-(D)-galactopyranosyl)-(1 -> 4)-(3,6-di-O-acetyl-2-deoxy-2-phthalimido-beta-(D)-glucopyranosyl)-( 1 -> 3)-(2,6-di-O-benzoyl-beta-(D)-gatactopyranosyl)-(1 -> 4)-2,3,6-tri-O-benzoyl-beta-(D)-glucopyranoside (4) was synthesized by regio-selective glycosylation of 4-pentenyl (2,6,-di-O-benzoyl-beta-(D)-galactopyranosyl)-(1 -> 4)-2,3,6-tri-O-benzoyl-beta-(D)-glueopyranoside and (2,3,4,6-tetra-O-acetyl-beta-(D)-galactopyranosyl)-(1 -> 4)-3,6-di-O-acetyl-2-deoxy-2-phthalimido-beta-(D)-glucopyranosyl chloride. By conversion of the protecting groups followed by thioacetylation, 4 was transformed into the corresponding lacto-N-neotetraose derivative, 5-(acetylthio)pentenyl (2,3,4,6-tetra-O-acetyl-beta-(D)-galactopyranosyl)-(1 -> 4)-O-(3,6-di-O-acetyl-2-acetamido-2-deoxy-beta-(D)-glucopyranosyl)-(1 -> 3)-(2,4,6-di-O-acetyl-beta-(D)-galactopyranosyl)-(1 -> 4)-2,3,6-tri-O-acetyl-beta-(D)-glucopyranoside (6). The lacto-N-neotetraose derivative 6 was introduced into carbosilane dendrimer cores of three shapes, and three kinds of new carbosilane dendrimers peripherally functionalized by lacto-N-neotetraose were obtained.
