The surfoxide esters 14 and 20d are successfully annulated with bicyclic enone 8 in the presence of (t)BuOLi to provide the pentacyclic ketones 9a and 21a respectively in good yields (≤70%). Flash vacuum pyrolysis of O-methyl derivatives 9b and 21b at - 5000 C/. 1 mm provide furoindacenones 16b and 22b respectively, which in turn are convertible to furocoumarins 1 and 3.
