cyanide to give the l-hydroxyazetidine 4f. Reduction of nitrone 1b to give the l-hydroxyazetidines 7 and 8 is achieved by reaction with lithiumaluminumhydride at 0°C and at room temperature, respectively. In contrast, nitrone 1d reacts with lithiumaluminumhydride only at 45°C to give the l-hydroxyazetidine 11. The differences in the reactivity of the nitrones 1 and 2 towards nucleophilic reagents
