Direct Palladium-Catalyzed Arylations of Aryl Bromides with 2/9-Substituted Py-rimido[5,4-b]indolizines. — The title reaction is sensitive to electronic effects. With the exception of 2-pyridinyl and 4-nitrophenyl, aryl bromides with electron-withdraw-ing substituents gave higher yields than those with electron-donating ones. Product (IIIg) exhibits moderate inhibition against Rh30 cells. — (JIANG, M.; LI, T.; MENG, L.; YANG*, C.; XIE, Y.; DING, J.; J. Comb. Chem. 11 (2009) 5, 806-808; State Key Lab.
