- Stereoselective Synthesis of the Benzodihydropentalene Core of the Fijiolides
-
An efficient stereoselective synthesis of the enantiomer of the benzodihydropentalene core of fijiolides A and B has been achieved. The asymmetric conjugate addition of styrylboronic acid to an indenone produced the first stereocenter. Ring C was installe
