Several new cyano-substituted derivatives with pyrrolo[1,2-a]quinoline and pyrrolo[2,1-a]isoquinoline scaffolds were synthesized by the [3 + 2] cycloaddition of (iso)quinolinium ylides to fumaronitrile. The cycloimmonium ylides reacted in situ as 1,3-dipoles with fumaronitrile to selectively form distinct final compounds, depending on the structure of the (iso)quinolinium salt. Eleven compounds were

3-unsubstituted pyrrolo[2,1-a]isoquinolines efficiently. Herein, we report a tandem reaction of the methyl(phenyl)vinylselenonium salt with isoquinoline and 2-bromoethanones to access 2,3-unsubstituted pyrrolo[2,1-α]isoquinolines efficiently and conveniently under mild conditions and in moderate to good yields. To the best of our knowledge, this is the first reported one-pot synthesis of the pyrrolo[2,1-a]isoquinolines
A new series of indolizine derivatives were synthesized and screened for the antiproliferative potential against NCI 60 tumor cell line panel. The results of the study revealed a selective and good antitumor growth inhibitory activity against SNB-75 CNS cancer cell line for 1-cyanoindolizine derivative 10b. Moreover, a supplementary in vitro biologicalevaluation showed that compound 9d exhibited a
An efficient, three-component strategy for the improved synthesis of a pharmaceutically interesting diverse kind of multi-functionalized benzofurans via one-pot two-step domino protocol with high diastereoselectivity in excellent yields has been established. The synthesis was achieved by reacting phenacyl bromides, N -heterocycles, aromatic aldehydes, and cyclic 1,3-dicarbonyl compounds in the presence

New pyrrolo[2,1-a]isoquinolines were obtained by two one-pot procedures via 1,3-dipolar cycloaddition between the isoquinolinium N-ylides and symmetrical acetylenic dipolarophiles, avoiding the formation of dihydro intermediates. For structural comparison, the dihydro derivatives obtained by a classical two-stage reaction were characterized by NMR and X-ray crystallography, allowing complete stereochemistry
