Rapid syntheses of either enantiomer of important carbocyclic nucleoside precursors

The syntheses of both enantiomers of aminocyclopentanetriol 1, a versatile carbocyclic nucleoside precursor, is reported utilizing an amino acid-derived acylnitroso Diels-Alder cycloaddition. The sequence is practical and proceeds in an overall yield of 36% from the D-alanine-derived hydroxamic acid. (C) 2000 Elsevier Science Ltd.

Method for preparing ticagrelor key intermediate

The invention relates to a chemical synthesis method of ticagrelor key intermediate 2-[[(3aR, 4S, 6R, 6aS)-6-aminotetrahydro-2,2-dimethyl-4H-cyclopenta-1,3-dioxolane-4-yl] oxy]ethanol (a key intermediate A). The method comprises the following steps: taking D-ribose as a raw material, and carrying out ten chemical reaction steps of 1-locus methylation and 2,3-loci isopropylidene protection, 4-locus derivatization, iodination, furan ring-opening, hydroxylamine reaction, palladium on carbon catalytic hydrogenation, amino Cbz protection, hydroxy protection, sodium borohydride reduction ester, Cbz removal protection and the like, thereby obtaining the key intermediate A. The raw materials are cheap and readily available, the preparation process is high in operability, steps of optical resolution, chiral induction and the like are avoided, the total yield is relatively high, and the product quality is better; particularly due to the use of sodium borohydride reduction ester, the preparation cost of ticagrelor is greatly reduced; and the method is suitable for large-scale industrial production.
