Foucaud,Brine
, p. 2851 - 2861 (1994)
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

scheme or table, p. 2971 - 2976 (2010/01/21)
Either [1,3]- or [3,3]-sigmatropic rearrangements were selectively accessed by controlling the reaction temperature in the gold(III)-catalyzed tandem rearrangement/cyclization of (E)-2-(aryloxymethyl)alk-2-enoates to afford diversely substituted 3,4-dihyd
TRIFLUOROACETIC ACID CATALYZED AND THERMAL REARRANGEMENT OF α-ARYLOXYMETHYL CINNAMIC ACIDS.
Krishnamoorthy, T. V.,Rajagopalan, K.,Balasubramanian, K. K.
, p. 1747 - 1748 (2007/10/02)
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.
