Worayuthakarn, Rattana published the artcileSynthesis of benzoindoloquinolizines via a Cu(I)-mediated C-N bond formation, Formula: C30H24BrCuN2P, the publication is Tetrahedron (2012), 68(13), 2864-2875, database is CAplus.
An effective synthesis of the multi ring-fused benzoindoloquinolizines has been accomplished by Cu(I)-mediated and MW-assisted C-Namide bond formation of benzo[a]quinolizin-4-ones. The deamination of tetrahydro-2H-pyrido[2,1-a]isoquinolines was also studied and was found to give benzoquinolizines. The benzo[a]quinolizin-4-ones were prepared based on the annulations of C-1 substituted 3,4-dihydroisoquinolines and azlactones.
Tetrahedron published new progress about 25753-84-8. 25753-84-8 belongs to bromides-buliding-blocks, auxiliary class Copper, name is Bromo(1,10-phenanthroline)(triphenylphosphine)copper(I), and the molecular formula is C39H35N5O8, Formula: C30H24BrCuN2P.
