Abstract
Some derivatives of the title heterocycles have been prepared by a "one step" synthesis from 2-hydroxy-2-acylmethylene-1,3-indandiones, tosyl chloride and isoquinoline or phthalazine. The synthesis of new indeno [2,1-b]indolizine derivatives performed by using pyridine as base is also reported.Keywords
