SmI2-promoted cyclizations of cyclic imides having 3-iodopropyl or 4-iodobutyl groups on the imide nitrogen have been studied for construction of nitrogen-fused polycyclic amides.

The pyrrolizindinone 2a was obtained from 1-bromo-3-(triphenylphosphoranylidene)-2-propanone and the anion of succinimide; reaction with the cyclopropylphosphonium bromide 7 gave the hydroxypyrrolizidinone 9.Functionalization of the "hydroxypyrrole" 2 yielded the derivatives 3-6.By regioselective acetoxylation of 9 (to yield 14) and subsequent Vilsmeier formylation the acetoxypyrrolizinecarbaldehyde 15 was obtined.
