Abstract

Abstract New synthetic approaches to substituted aromatic compounds are reported. Ring- closing olefin metathesis (RCM)/dehydration and RCM/tautomerization are the key processes in the synthesis of substituted benzenes 3 and phenols 6, respectively. Readily accessible 1, 5, 7-trien-4-ols 7, which are the precursors of benzenes, were prepared from β- halo-α, β-unsaturated aldehydes 11 or β-halo-α, β-unsaturated esters 19 by utilizing ...
