A facile synthesis of highly functionalized 4-arylcoumarins via kostanecki reactions mediated by DBU

An efficient synthesis of 4-arylcoumarins has been accomplished via Kostanecki reactions of 2-hydroxybenzophenones with acetic anhydride employing DBU at ambient temperature. Using the same strategy, several 2-acyloxybenzophenone derivatives were readily converted to 3,4-difunctionalized coumarins. This protocol offers a notable improvement in reaction conditions for coumarin synthesis and takes advantage of its synthetic capability, especially for highly functionalized 4-arylcoumarins with structural diversity.

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.
