  An intramolecular N-arylation approach to 3-functionalized 4,9-dihydropyrrolo[2,1-b]quinazolines

  摘要：

  AbstractA series of 4,9‐dihydropyrrolo[2,1‐b]quinazolines containing electron withdrawing groups at the 3‐position have been prepared by the palladium‐catalyzed intramolecular N‐arylation of some 2‐aminopyrroles having a 2‐bromobenzyl group at the N‐1 position. Important for success of the reaction is the use of X‐phos, a biphenyl mono‐phosphine ligand, instead of xantphos, a more standard diphosphine ligand, and the use of t‐BuOH as reaction solvent. J. Heterocyclic Chem., (2011).
