  • Alkylation of Partially Protected Xylofuranoses and Tetritols with (2,2,3,3,4,4,5,5,6,6,7,7,7-Tridecafluoroheptyl)oxirane and the Stability of Protecting Acetal Groups Towards Lewis Acid-Type Catalyst

    1,2-O-Isopropylidene-3-O-methyl-α-D-xylofuranose (2), 1,2-O-isopropylidene-α-D-xylofuranose (3), 2,4-O-ethylidene-D-erythritol (4) and 1,3-O-ethylidene-D-threitol (5) were alkylated with racemic (2,2,3,3,4,4,5,5,6,6,7,7,7-tridecafluoroheptyl)oxirane (1) using boron trifluoride diethyl etherate as a catalyst. The desired mono- or disubstituted polyfluoroalkyl derivatives 6-11 were isolated only in low to medium yields. The fluoroalkylation was accompanied with disproportional distributions of the protecting acetal/ketal groups and polymerization of saccharides. Therefore the stability of 3, 4, 5, 5-O-acetyl-1,2-O-isopropylidene-α-D-xylofuranose (14) and 1,2-O-isopropylidene-α-D-glucofuranose (15) in the presence of a catalytic amount of boron trifluoride diethyl etherate was investigated in various solvents. A mechanism explaining the effect of the catalyst has been proposed.

    1,2-异丙基亚甲基-3-甲氧基-α-D-木糖呋喃糖(2),1,2-异丙基-α-D-木糖呋喃糖(3),2,4-乙基亚甲基-D-赤霉醇(4)和1,3-乙基亚甲基-D-甘露醇(5)被使用三氟化硼乙醚酸酯作为催化剂与外消旋(2,2,3,3,4,4,5,5,6,6,7,7,7-十三氟庚基)环氧丙烷(1)发生烷基化反应。所得的单取代或双取代的多氟烷基衍生物6-11只以低至中等收率分离。氟烷基化反应伴随着保护缩醛/缩酮基团的不均匀分布和糖苷的聚合。因此,在各种溶剂中研究了3,4,5,5-乙酰基-1,2-异丙基-α-D-木糖呋喃糖(14)和1,2-异丙基-α-D-葡萄糖呋喃糖(15)在存在少量三氟化硼乙醚酸酯的情况下的稳定性。提出了解释催化剂作用的机制。
  • Stereoselective allylation for preparation of L-hexose derivatives
    作者:D.R. Williams、Franz D. Klingler
    DOI:10.1016/s0040-4039(01)81010-8
    日期:1987.1
    The reaction of allyltrimethylsilane with α,β-dialkoxyaldehydes is catalyzed by magnesium bromide, and provides for a highly stereoselective allylation which is predicted by α-chelation of the Lewis acid. The observed stereocontrol is opposite to that generally obtained from a variety of common allylation reagents.

    日期:——
    The addition reaction of dimethyl phosphonate to (2R,4S)-4-(tertbutyldimethylsilyl)oxymethyl-2-methyl-1,3-dioxan-5-one (11a), followed by dehydroxylation, provided 1-O-(tert-butyldimethylsilyl)-3-deoxy-3-dimethoxyphosphinoyl-2,4-O-ethylidene-D-erythritol (13a). Elongation of carbon skeleton of the D-erythrose (14) derived from 13a and then acidic methanolysis gave a mixture of methyl 2,4-dideoxy-4-dimethoxyphosphinoyl-alpha,beta-D-erythropentopyranosides (7), which was led to 2-deoxy-D-ribofuranose phospho sugar (4) in an appreciably improved total yield compared with the procedures via previously reported route.
