AB  - The synthesis of triptindans 13a - e substituted by methoxy and/or methyl groups in positions 2,4,5,7,13, and 15 has been achieved by acid-catalysed cyclodehydration of the corresponding 2,2-dibenzyl-1-indanones 12a - e using Amberlyst 15 and polyphosphoric acid, respectively. Total demethylation of 13a followed by selective deoxygenation of the resulting hexahydroxy compound 14 affords the 4,5,15-trihydroxytriptindan (17) (4, R=OH) bearing the three substituents in its molecular cavity.
