One-Pot Oxidation/Isomerization of Z-Allylic Alcohols with Oxygen as Stoichiometric Oxidant
摘要:
A method for generating (E)-alpha,beta-unsaturated aldehydes from Z-allylic alcohols or E/Z-mixtures is described. The one-pot procedure involves a Cu-catalyzed oxidation followed by an organocatalytic DE-isomerization with N,N-dimethylaminopyridine (DMAP).

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.
