Abstract

Carbanions of 3-chloropropyl pentachlorophenylsulfone, although they undergo fast cyclization to the corresponding cyclopropyl sulfone, can be trapped with electrondeficient alkenes to produce carbanionic adducts that enter intramolecular substitution to form substituted cyclopentanes.

Key words

carbanions - cyclization - cyclopentane - Michael acceptors - sulfone

Typical Procedure. All reactions were performed in oven-dried glassware under argon. THF was freshly distilled from potassium-benzophenone. To a solution of 1 (117 mg, 0.3 mmol) in THF (5 mL) at -70 °C LDA (0.22 mL of 1.8 M solution, 0.4 mmol) was added in one portion. After 1-2 sec Michael acceptor dissolved in THF was added: 0.45 mmol in 0.5 mL of THF for the synthesis of 4, 7, 8, 9, 10; 0.6 mmol for 6, and 3 mmol for 5. The mixture was stirred for 5 min, warmed to r.t., quenched with aq NH₄Cl, extracted and purified by column and preparative TLC chromatography (hexane/EtOAc as eluent).
