Name is 3,4-Di(1H-indol-3-yl)-1H-pyrrole-2,5-dione, as a common heterocyclic compound, it belongs to chiral-nitrogen-ligands compound, and cas is 119139-23-0, its synthesis route is as follows.
Example 1 12,13-(2,3-dihydroxy-butan-1,4-yl)-6,7,12,13-tetrahydro-5-oxo-5H-indolo[2,3-a]pyrrolo[3,4-c]carbazole (Compound 14) Palladium dichloride (7.4 g, 41.6 mmoles) was added to a solution of acryrubin A Compound 1a (2.9 g, 8.86 mmol) (prepared as described in Faul M M, Winneroski L L and Krumrich C A, Journal of Organic Chemistry, 1998, 63, 6053-6058) in DMF (100 mL) at 90 C. The reaction temperature was kept at 90 C. for 1 hr. The mixture was cooled and conc. HCl (50 mL), then water (50 mL) was added. The mixture was poured over ice and the resulting precipitate was filtered off. The solids were washed with H2O and MeOH, then dissolved in THF (200 mL) and acetone (200 mL) and the remaining solids were filtered off. The solution was filtered through a plug of silica gel and the solvent was removed under vacuum. The resulting residue was diluted with MeOH, the solids were filtered and washed with MeOH then dried to provide acryflavin A Compound 1b (2 g, 70%) as a brown solid.
119139-23-0, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,119139-23-0 ,3,4-Di(1H-indol-3-yl)-1H-pyrrole-2,5-dione, other downstream synthetic routes, hurry up and to see
