  名称：

  Stereoselective preparation of O-alkoxy d-tetrose, d-pentose, 2-deoxy-d-glycero tetrose and 2,3-dideoxy-d-erythro pentose derivatives by an iterative elongation of 2,3-O-isopropylidene-d-glyceraldehyde

  摘要：

  All D-pentoses are synthesized by one-carbon chain elongation commencing with the addition of the lithium salt of ethyl ethylthiomethyl sulfoxide to 2-O-(t-butyldimethylsilyl)-3,4-O-isopropylidene-D-erythrose and D-threose, 16 and 17. The addition of the above-mentioned nucleophile to 2-deoxy-3,4-O-isopropylidene-D-glycero tetrose, 19, gave rise to 2,3-dideoxy-D-glycero pentose. The starting aldehydes, 16, 17 and 19, are easily available from 2,3-O-isopropylidene-D-glyceraldehyde, 1, and ethyl ethylthiomethyl sulfoxide. (C) 1999 Elsevier Science Ltd. All rights reserved.

  Analysis of the reactivity of the dithioacetal mono-S-oxide 1-deoxy-1-ethylsulfinyl-1-ethylthio-3,4-O-isopropylidene-D-erythritol under different conditions of reduction

  摘要：

  The chemistry of dithioacetal mono-S-oxides has not been studied very frequently. Their usual chemistry aims at recovering the carbonyl function by a sequence of reduction and hydrolysis. The results of the transformation of the dithioacetal mono-S-oxides of 1-deoxy-1-ethylsulfinyl-1-ethylthio-3,4-O-isopropylidene-D-erythritol, 2, under different reduction conditions, are reported in this paper. We also report how the coexistence of functional groups influences the resulting products. Hence, reductions with LiAlH4, Ph(3)P, (Me(2)N)(3)P, (CF3CO)(2)O-NaI and AcONa-Ac2O under Pummerer-type rearrangements have been studied.
