Ag. Moglioni et Gym. Iglesias, STRUCTURE DETERMINATION OF 2-(2',3'-DIHYD DIMETHOXY-1'H-INDEN-1'-YL)-5,6-DIMETHOXY-1H-INDENO, Anales de la Asociacion Quimica Argentina, 85(1-2), 1997, pp. 77-79
The process of one carbon homologation of 5,6-dimethoxy-indan-1-ol aff
orded an unexpected product that by comparison with one present in the
literature was assigned as dimethoxy-1'H-inden-1'-yl)-5,6-dimethoxy-1
H-indene 1. Now we show by synthesis that the structure 1 was wrong an
d the correct one corresponds to dimethoxy-1'H-inden-1'-yl)-5,6-dimeth
oxy-1H-indene 4.
