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-4H-cyclopenta[b]thiophene-6-carboxylate [(±)-14]. The target compounds were obtainedtogether by direct reduction of (±)-14 with AlH3 in refluxing
