Cagniant, Paul; Kirsch, Gilbert published an article in 1976, the title of the article was Method for the synthesis of mono- or polysubstituted 3(2H)-benzofuranones and benzo[b]furans.Name: 5-Iodobenzofuran And the article contains the following content:
Benzofurans I (R = H, Me; R1 = 7-Me, 6-Me, 6-OMe, 5-OMe, 5-SMe, 5-F, 5-I; R2 = H) were prepared by alkylating the salicyclic esters II (R3 = H) with BrCHRCO2Et, hydrolyzing II (R3 = CHRCO2Et), cyclizing the diacids with AcONa-AcOH-Ac2O, hydrolyzing I (R2 = OAc), reducing III (X =O), and dehydrating III (X = H,OH). I (R = Ac, R2 = OAc) were obtained as byproducts of I (R = H,Me, R2 = OAc). The experimental process involved the reaction of 5-Iodobenzofuran(cas: 60770-67-4).Name: 5-Iodobenzofuran
The Article related to benzofuran, salicylate carboxyalkoxy cyclization, carboxyalkoxysalicyclate cyclization, Heterocyclic Compounds (One Hetero Atom): Areno- and Diarenofurans and other aspects.Name: 5-Iodobenzofuran
