✦ Synopsis


A stereo-divergent synthetic strategy based on diastereoselective vinylation of an a-amino aldehyde, ring-closing metathesis reaction and diastereoselective dihydroxylation reaction as key steps has been developed for the synthesis of three aminocyclopentitol derivatives of chemical and biological relevance.

## Abstract New pyrrolizidine derivatives 6 and 7 were prepared from the 1, 5‐dihydro‐2__H__‐pyrrol‐2‐one 3a __via__ an acidic intramolecular aldol condensation in 16% and 42% yields, respectively. Compound 6 was obtained by dehydration of 7 with __p__‐toluenessulfonic acid in 67% yield.
