The racemic heterobicyclic amino alcohols 6 and 7 , which are of interest as intermediates in the synthesis of nucleoside analogues with heterobicyclic pseudosugars, were efficiently prepared from 2‐thienylsuccinic acid via methyl 4‐hydroxyimino‐5,6‐dihydro‐4 H ‐cyclopenta[ b ]thiophene‐6‐carboxylate [(±)‐ 14 ]. The target compounds were obtainedtogether by direct reduction of (±)‐ 14 with AlH 3 in refluxing THF, and were separated by flash chromatography of their N ‐acetylated derivatives.(© Wiley‐VCH Verlag GmbH & Co.
