  Highly stereoselective synthesis of C-vinyl furanosides through acid-catalyzed SN2 inversion at the C-3 position of 1,2-dideoxy-hept-1-enitols

  摘要：

  A highly stereoselective synthesis of C-vinyl furamosides through the S(N)2 inversion at the C-3 position of the 1,2-dideoxy-hept-1-enitols is disclosed. Treatment of the 1,2-dideoxy-hept-1-enitols with diphenylammonium trifluoromethanesulfonate as the acid catalyst produced the C-vinyl furanosides (3,6-anhydro-1,2-dideoxy-hept-1-enitol derivatives) via a subsequent S(N)2 intramolecular debenzyloxyationcycloetherification reaction at the C-3 position.

  The first construction of a 3,6-bridged ellagitannin skeleton with 1C4/B glucose core; synthesis of nonamethylcorilagin

  摘要：

  The synthesis of nonamethylcorilagin is described. In the synthesis, the intramolecular Ullmann coupling afforded the (R)-hexahydroxydiphenoyl part-a characteristic bridge structure of the target molecule-when the glucopyranose ring was opened in advance. This synthesis demonstrates the first synthetic approach to a 3,6-bridged ellagitannin skeleton whose conformation of the D-glucose core is C-1(4) or skew boat. (C) 2003 Elsevier Ltd.

  An object of the present invention is to provide a 3,6-O-bridged pyranose-inverted compound useful for being easy to produce β-O-pyranosides selectively. The 3,6-O-bridged pyranose-inverted compound according to the present invention is represented by General Formula (1): wherein R A and R B each represent hydrogen or are bonded to each other to form a benzene ring; one of R C and R D represents hydrogen and the other represents —OR 2 ; R 1 represents hydroxy or halogen; and R 2 and R 3 each represent a hydroxy-protecting group.

  本发明的一个目的是提供一种3,6-O-桥联吡喃糖倒置化合物，用于易于选择性地生产β-O-吡喃糖苷。根据本发明，3,6-O-桥联吡喃糖倒置化合物由通式（1）表示：其中RA和RB分别表示氢原子或结合在一起形成苯环；RC和RD中的一个表示氢原子，另一个表示—OR2；R1表示羟基或卤素；R2和R3各自表示一个羟基保护基团。

  A completely β-selective glycosylation that does not rely on neighboring group participation is described. The novelty of this work is the design of the glycosyl donor locked into the axial-rich form by the o-xylylene bridge between the 3-O and 6-O of d-glucopyranose. The synthesized 2,4-di-O-benzyl-3,6-O-(o-xylyene)glucopyranosyl fluoride could efficiently react with various alcohols in a SnCl(2)-AgB(C(6)F(5))(4)

  描述了一种不依赖于相邻基团参与的完全 β 选择性糖基化。这项工作的新颖之处在于设计的糖基供体通过 d-吡喃葡萄糖的 3-O 和 6-O 之间的邻二甲苯桥锁定为富含轴向的形式。合成的 2,4-di-O-benzyl-3,6-O-(o-xylyene) 吡喃葡萄糖基氟可以有效地与 SnCl(2)-AgB(C(6)F(5))( 4）催化体系。通过使用酸性和碱性分子筛的比较实验揭示了由糖基化和异构化循环组成的机制。实现的完美立体控制归因于富含轴向的构象和由原位生成的 HB(C(6)F(5))(4) 引起的收敛异构化的协同作用。

  DOI：10.1021/ja803111z

  日期：2008.6.18

  The synthesis of corilagin was achieved by the integration of the development of the oxidative coupling of the symmetrically protected gallates and the temporarily ring-opened synthetic route for the 3.6-hexahydroxydiphenoyl (HHDP) bridge. This is the first total synthesis of the C-1(4)/B-ellagitannins, which contain ring-flipped glucose.
