Photochemical reaction of benzofuran derivatives with benzophenone or benzaldehyde was written by Kawase, Yoshiyuki;Yamaguchi, Seiji;Ochiai, Hirokazu;Horita, Hisanori. And the article was included in Bulletin of the Chemical Society of Japan in 1974.HPLC of Formula: 1646-27-1 This article mentions the following:
Photochem. reaction of the benzofurans I [R = R1 = Me; R = Me, CH2OH, R1 = H; RR1 = (CH2)4] with benzophenone gave the oxetanes II (R2 = Ph). Oxetanes II (R2 = H) were produced by the reaction of I with benzaldehyde, but yields were not so high because of their instability. The reaction of 2-methoxycarbonyl- and 2-cyano-benzofuran with benzophenone or benzaldehyde gave dimers of the benzofurans. In the experiment, the researchers used many compounds, for example, Methyl benzofuran-2-carboxylate (cas: 1646-27-1HPLC of Formula: 1646-27-1).
Methyl benzofuran-2-carboxylate (cas: 1646-27-1) belongs to benzofurans derivatives. Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. Introduction of benzofurans in organic synthesis, particularly drug synthesis, involves generally the use of their metalated species as nucleophiles in addition reactions or in metal-catalysed cross-coupling reactions.HPLC of Formula: 1646-27-1
