[摘要]:Esters of 4,9-dihydro-2H-benz[2,3-f] isoindole-1-carboxylate and 4,11-dihydro-2H-naphth[2,3-f]isoindole-1-carboxylate were prepared by the modified Barton-Zard reaction of 2,3-bis(phenylsulfonyl)-1,2,3,4-tetrahydro-naphthalene and anthracene with isocyanoacetate esters, respectively. The bis(phenylsulfonyl) derivatives were, in turn, prepared by the pericyclic reactions of the corresponding sultines with trans-1,2-bis(phenylsulfonyl)ethylene. The pyrrole esters were converted to the corresponding mono-naphthoporphyrin and mono-anthraporphyrin in good overall yields. |
