Relevant academic research and scientific papers

From phenylacetylphenylacetic acids and 1-benzylisoquinolines to 6,11-dihydrobenzo[b]naphtho[2,3-d]furan-6,11-diones, 6H-dibenzo[c,h]chroman-6-ones and 7,12-dihydro-5H-dibenzo[c,g]chroman-5,7,12-triones via 2-phenyl-3-hydroxy-1,4-dihydro-1,4-naphthalenediones or 2-phenyl-1-naphthols

We describe the synthesis of 6,11-dihydrobenzo[b]naphtho[2,3-d]furane-6,11-diones, 6H-Dibenzo[c,h]chroman-6-ones and 7,12-dihydro-5H-dibenzo[c,g]chroman-5,7,12-triones from 2-(2'-phenyl)-3-hydroxy-1,4-dihydro-1,4-naphthalenediones or 2-phenyl-1-naphthols obtained from 2-(2'-bromophenylacetyl)-phenylacetic acids or 1-benzylisoquinolines.
