A convenient Pictet-splengler approach for the synthesis of substituted pyrrolo[1,2-a]quinoxaline from aryl amines and 1-(2-aminoaryl)-pyrrole has been developed. This is the first domino protocol involving formation of benzaldehyde as an intermediate from benzyl amines and benzyl alcohols using 1,2-DNB as an oxidant, followed by its endo cyclization with 1-(2-aminophenyl)-pyrrole to furnish the pyrrolo[1
Embodiments concern methods and small molecule compositions for selectively inhibiting RAD51-mediated D-loop formation while preserving RAD51's ability to form nucleoprotein filaments. The selective RAD51 D-loop formation activity inhibitors DNA repair while minimizing replication-associated toxicity in normal tissue.
