Indolizines with dye properties and synthesis process such indolizines

摘要

Indolizines with dye properties and synthesis process such indolizines. # Has been found a very novel transformation method indolizines 1,3-disubstituted 1,3,7-trisubstituted indolizines of greater structural complexity, by high conjugation, absorb radiation in the visible spectrum. Indolizine type obtained is again structurally presents reddish orange color solid state sample solvatochromic effect and is selectively obtained in good yields. The main feature of this methodology is that the products are prepared by transforming a single starting material, indolizine, which grows structurally from itself by an acid / base treatment. In addition, the fact that the case of new molecular structures and these are solvatochromic, leaves open the possibility of studying potential applications.
