We describe the first studies on the chemistry of 2-(2-oxo-3-phenylpropyl)benzaldehydes, which were converted into 3-benzylisochromen-1-ones via the corresponding 2-(2-oxo-3-phenylpropyl)benzoic acid. The 2-(2-oxo-3-phenylpropyl)benzaldehydes proved to be convenient starting materials for the synthesis of 3-phenyl-2-naphthols. Oxidation of the latter compounds resulted in a novel, efficient synthesis...
We describe two total syntheses of 1-methyl-1,2,3,4-tetrahydronaphtho[1,2-f]isoquinolines based on free radical cyclization. One of them includes the cyclization of N-{2-[2-(2-bromophenyl)-1-methoxyethyl]phenylethyl}acetamides and subsequent transformation of the resulting N-[2-(10-methoxy-9,10-dihydro-1-phenanthryl)ethyl]acetamides. The second is based on the known cyclization of 1-(2-bromobenzyl)isochroman-3-ones...
