The vinylvicinaltricarbonyl system 1 (VTC) has been used in two different approaches to prepare functionalized indolizidines. In one approach, 1 is used as a trielectrophile in reactions with primary amines possessing auxiliary donor sites. In a second approach, 1 is converted to a substituted 3-hydroxypyrrole-2-carboxylate. This pyrrole derivative then undergoes an intramolecular alkylation to give

The four diastereomers of 1-hydroxyindolizidine have been prepared in high optical purity (>98%) by NaBH4 reduction of the (+) and (-) 3-bromocamphor-8-sulfonic acid salts of 1-oxoindolizidine followed by separation of the resulting diastereomeric alcohols by ion-exchange chromatography.
