Samarium(II) iodide-induced tandem reductive coupling-Dieckmann condensation reaction: one-step synthesis of bicyclic oxacyclopentanecarboxylate from bis-α,β-unsaturated esters
The tandem cyclization of bis-α,β-unsaturated esters with SmI2-Sm–THF in the presence of catalytic amount of methanol was found to stereoselectively provide bicyclo[4.3.0]nonan-8-ones and bicyclo[3.3.0]octan-3-ones.

Electrochemical cyclisation of methyl cinnamate with dielectrophiles has been improved by the presence of an aluminum salt which was pre-formed in situ by the electrolysis of a carboxylic acid with a sacrificial aluminum anode. High yields of three, five and six-membered cyclic products have been obtained in the reactions of methyl cinnamate with dichloromethane, 1,3-dibromopropane, and 1,4-dibromobutane.
