Tributyltin(IV) hydride mediated free-radical syntheses of dehydrodibenzochromanones, dehydrodibenzocoumaranones and aristolactams
摘要:
We describe free radical cyclization of methyl bromophenylacetylphenylacetates to novel dehydrodibenzo[de,g]chromanones; oxidation of the latter compounds allowed the first total synthesis of dehydrodibenzo[cd,f]coumaranones, which are easily transformed into aristolactams.
