Rapid Access to a Series of Highly Functionalized α,β-Unsaturated Cyclopentenones. A Caveat on Aminospirocyclization

Conjugate addition of a series of functionalized aryllithium reagents to cyclopentenyl sulfones 9 and 17 results in α-sulfonyl anion intermediates taht are further alkylated to afford triply converged adducts 12a-c and 19.Refunctionalization of these adducts provides α,β-unsaturated cyclopentenones 4a-c and 21 in high overall yields.Attempted intramolecular Michael addition of these (γ-aminopropyl)cyclopentenones to produce the spiro ring system was unsuccessful.

An Investigation of the Chemistry of Phenylsulphonylcyclopentadiene

Phenylsulphonylcyclopentadiene (7) exists mainly as the 1-isomer, and the assigned structure of its dimer (6) has been corroborated by n.m.r. decoupling experiments.Both the diene (7) and its cyclopentadienide anion (8) were unusually unreactive, although
