TL;DR: In this paper, aldol condensation at 70° between 11-diethoxy-2-lithio-2propene and 2,3- O -isopropylidene-D - glyceraldehyde was used to obtain precursors of C-2 branched-chain pentoses.

TL;DR: The electrochemical one-electron oxidation of 9-hydroxy-ellipticinium cations at a platinum electrode has been examined with particular attention to the thermodynamic redox potential and to the dimerization rate of the radical species produced as mentioned in this paper.

TL;DR: In this paper, 4-Deoxytetroses and arabino pentoses having Me-, Et-, HOCH 2 -, N 3 Ch 2 - and H 2 NCH 2 −2 were synthesised by stereospecific epoxidation of 3-hydroxy-2-methylene sugar diethyl acetal derivatives, followed by regiospecific opening of the epoxide by various nucleophilic reagents.
