  Direct synthesis of mono-glycosylated catechols from glycosylacetates or imidates using BF3.OEt2 as catalyst

  摘要：

  The coupling of 3-n-alkylcatechols to the acetate or trichloroimidate derivatives of beta-D- or alpha-D- sugars (glucose, galactose. xylose, mannose and maltose) catalysed by BF3.OEt2 has been studied. Beta sugars with an equatorial acetate group at position 2 formed exclusively beta adducts with yields of 60-80%. Alpha sugars with an equatorial acetate group at position 2 formed beta adducts, while beta sugars with an axial acetate group formed alpha adducts when activated as trichloroimidates, with yields of 70-85%. Two mechanisms to explain these results are proposed.

• Synthesis of 3-Alkylcatechols via Intramolecular Cyclization
  作者：Tetsuo Miyakoshi、Hiroyasu Togashi

  DOI：10.1055/s-1990-26889

  日期：——

  The intramolecular cyclization of 2-alkanoyl-2,5-dimethoxytetrahydrofurans 4 with aqueous acid is described. 3-Alkylcatechols 7 were prepared in generally good yields by boiling the dioxane solution of compounds 4 in the presence of 1M hydrochloric acid. In addition, 4,5-dioxoalkanals 6 were obtained in good to high yields when the dioxane solution of compounds 4 was treated with 0.1 M hydrochloric acid.

  A series of soluble α-diimine late transition metal catalysts has been invented comprising a substituted or unsubstituted catecholate ligand. The catalysts demonstrate high activity and selectivity for linear α-olefins. As such, these catalysts conveniently oligomerize ethylene. Typical activators as known to those of ordinary skill in the art are used to activate these transition metal catalysts. These catalysts can be used in a supported or unsupported form.
