Abstract The carbonylative cross coupling of aryliodide with ortho-haloaniline to ortho-haloanilide usingphosphine-freePd(OAc)2 catalyst in water as a reaction medium has been studied. The present protocol facilitated the reaction of o-haloanilines with a wide variety of hindered and functionalized aryliodides, affording good yields of the desired products. The protocol was also extended for the

By using diaryliodoniumsalts, a cylization has been accomplished in the synthesis of N-aryl phenanthridinone derivatives via a cascade of ortho-arylation and Csp2-N bond formation in the presence of palladium catalyst. The reaction exhibits a broad compatibility of readily available N-arylnaphthamides.
Synthesis of Fused Tetracyclic Compounds via Oxidative Annulation: Access to Copper-Catalyzed Indolo[1,2-<i>a</i>]quinolines and to Ruthenium-Catalyzed Isoquinolin-1[2<i>H</i>]-ones
facile double oxidative annulation of (en-3-yn-1-yl)phenylbenzamides was developed allowing us to synthetize fused tetracyclic compounds. Under copper catalysis, the reaction proceeds with high efficiency and leads to new indolo[1,2-a]quinolines via a decarbonylative double oxidative annulation. On the other hand, under ruthenium catalysis, new isoquinolin-1[2H]-ones were obtained via a double oxidative
开发了 (en-3-yn-1-yl) 苯基苯甲酰胺的简便双氧化环化,使我们能够合成稠合四环化合物。在铜催化下,反应高效进行,并通过脱羰双氧化环化反应生成新的吲哚并[1,2- a ]喹啉。另一方面,在钌催化下,通过双重氧化环化得到了新的异喹啉-1[2 H ]-酮。
Structural development studies of anti-hepatitis C virus agents with a phenanthridinone skeleton
A phenanthridinone skeleton was derived from our previous researches on thalidomide and retinoids as a multi-template for generation of anti-viral lead compounds. Structural development studies focusing on anti-hepatitis C virus activity afforded 5-butyl-2-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)phenanthridin-6(5H)-one (10) and 5-butylbenzo[b] phenanthridin-6(5H)-one(39), which showed EC50 values of approximately 3.7 and 3.2 mu M, respectively.

We present the synthesis of OH-functional and balky N-substituted benzazophospholes, novel pyrido-azaphospholes, addition versus CH-metalation by tBuLi and reactions with electrophiles yielding a novel asymmetric P,N-heterocyclic ethylene-1,2-bis(phosphine) and phosphino-functional benzazaphospholes for hemilabile sigma(3),sigma(2)-P,P' coordination.
