Abstract
The synthesis of diethyl (3-alkyl-5-oxo-4,5,6,6a-tetrahydro-1H-cyclopenta[c]furan-4-yl)phosphonates from the corresponding 3-allyloxy-1-propynylphosphonates is described. The in situ reaction involves two steps: an intramolecular Pauson-Khand reaction followed by an unusual double bond deconjugation mediated by molybdenum hexacarbonyl in dimethyl sulfoxide.
Key words
double bond isomerization - molybdenum - phosphonate - Pauson-Khand reaction - deconjugation

Different sets of reaction conditions were examined during the optimization studies. We observed that after the formation of intermediate 2, from 1, using two equivalents of Mo(CO)6 and 10 equivalents of DMSO in toluene at 100 ˚C for one hour, the presence of toluene slowed down the rate of conversion of 2 into 3. Hence, toluene was evaporated at this stage.
