A novel parent BN-benzo[c]phenanthrene, with helical chirality and remarkable structural features, has been easily obtained in three steps with a global yield of 55%. Moreover, Cl-substituted derivatives have been prepared and these have served as useful starting materials for the development of palladium-catalyzed cross-coupling reactions.

2-propanedioic acids(2a-c) were denitrocyclized to coumarins (3a-c) by heating in quinoline in the presence of copper powder. 2-(4-Methoxiphenyl)-3-(2-nitrophenyl)-(Z)-2-propenoic acids (6a,b,d,e) were also similarly denitrocycli
