New Mansonone analogues of 9-substitued benzo[de]chromene-7,8-dione 5b-e and 5-benzyl-9-substitued benzo[de]chromene-7,8-dione 6a-e were prepared through a modified route. The first step involved a bulky base t-butylamine mediated regioselective deacetylation of 2-substituted-1,4-naphth-diyl diacetate, resulting in obtaining of monoacetate 4-acetate 2 in high yield. The mechanism of cyclization, debenzylation, and oxidation for the formation of 5a-e and 6a-e were discussed. The cytotoxicity of the prepared compounds 5 and 6 were comparable with naturally occurring Mansonone F. Copyright Taylor & Francis Group, LLC.
