Reactivity of Chiral α-Amidoalkylphenyl Sulfones with Stabilized Carbanions.
Synthesis of Optically Active 1-Aminopyrrolizidine. — Chiral sul08- 201 Stereoselective
fones of type (I) undergo coupling with metal enolates and alkylzinc reagents with good
to high anti selectivity. The resulting products are useful synthons: for example, (IIIa)
can smoothly be converted into the aspartate (IV) and starting from (XIIIc) enantioselective synthesis of 1-aminopyrrolizidine (XIV), a precursor of various biologically
active compounds, is possible. — (GIRI, N.; PETRINI*, M.; PROFETA, R.; J. Org.
