The synthesis of stilbenoids and styryl carboxylic acids is accomplished with high E-stereoselectivity by olefination of aldehydes with thiophthalides under basic conditions. The olefination is highly atom-efficient as it only loses elemental sulfur during the reaction. This olefination, in conjunction with retro Kolbe-Schmitt reaction, allows facile synthesis of E-hydroxystilbenoids with minimal employment of protecting groups. This study also discloses two important findings: formation of i) 4-methylsulfanyl isocoumarins and ii) an 2-arylindenone. The Royal Society of Chemistry 2012.
Chemical transformation from dihydroisocoumarin into benzylidene-phthalide by use of regiospecific oxidative lactonization mediated by copper chloride (H) - Syntheses of thunberginol F and hydramacrophyllol A and B

Oxidative lactonization of 2-carboxystilbene mediated by CuCl2 proceeded regiospecifically to give the five-membered lactone. By utilizing this lactonization as a key reaction, chemical transformation from dihydroisocoumarine into benzylideneph
