The Heck-oxyarylation of racemic 2-phenyl-2H-chromene [(±)-4b] and 1 2-dihydronaphthalenes (14a,b) has been studied with 2-chloromercuriphenols (5a-d) in the presence of Li2[PdCl4] catalyst The reactions resulted in the diastereoselective formation of racemic 6-phenylpterocarpans of (6R 6aR, 11aR) relative configuration [(±)-8a-d] and their dibenzo[1 3]dioxocine analogues [(±)-12a-d] as main products respectively The ratio of products and the lack of regioisomeric products (13a-d) corroborated the cationic mechanism of the oxyarylation of 2H-chromenes which has been also supported by the transformation of 14a,b under similar conditions.
