Abstract
Several new polyhydroxylated alkaloids including pyrrolidines with a long side chain and 3-(hydroxymethyl) indolizidines were prepared from a common nitrone easily obtained from d-arabinose. In addition, a total synthesis of hyacinthacine A 2 has been achieved in five steps and 67.7% overall yield starting from the same d- arabino-derived nitrone. All synthesized compounds have a common structural feature consisting of a pyrrolidine ring with d- arabino configuration.
