Synthesis of 3-arylidene-3,4-dihydrocoumarins

Methyl 3-aryl-3-hydroxy-2-methylene propionates react with phenols, 2-naphtol, 1,4-dihydroxybenzene, 2,3-dihydroxynaphtalene and 2,7-dihydroxynaphtalene in the presence of silica gel-supported ZnBr2 or FeCl3 to give 3-arylidene-3,4-d

TRIFLUOROACETIC ACID CATALYZED AND THERMAL REARRANGEMENT OF α-ARYLOXYMETHYL CINNAMIC ACIDS.

Several α-aryloxymethyl cinnamic acids 1 have been rearranged in refluxing trifluoroacetic acid (TFA).The thermal rearrangement of the same acids in polyethylene glycol-200 (PEG-200) has also been investigated.
