Enantiospecific approach toward pentalenolactone

The enantiospecific assembly of the pentalenolactones' carbon skeleton was achieved in 17 steps and 16% overall yield from methyl α-D- glucopyranoside. The synthetic strategy relies on two highly efficient key steps: an exo-diastereoselective Diels Alder
