Synthesis and Cytotoxic Studies of Pyrrolopyrimidine Derivatives

The synthesis and in vitro cytotoxicity of new pyrrolopyrimidine derivatives is reported in this work. All the compounds were characterized by IR, NMR and MS. They are examined for cytotoxic activity against HeLa. Pyrrolopyrimidine derivatives of benzyl amine (8g) and 4-bromoaniline (8k) showed a potent activity, which is comparable to that of standard Sorafenib.

A Novel Copper-Catalyzed Synthesis of N-Monosubstituted 2-Alkynimidamides from 1-Alkynes and Trichloroacetamidines

A one-pot Cu-catalyzed synthesis of functionalized alkynyl imidamide by terminal alkynes, trichloroacetonitrile and aniline or benzyl amine is reported. The compounds were produced via coupling reaction of terminal alkynes with trichloroacetamidine. This method was performed under mild, ligand-free conditions and easy work-up method.

Pd-Catalyzed C4-Dearomative Allylation of Benzyl Ammoniums with Allylstannanes

A dearomative C4-allylation of benzyl ammoniums with allylstannanes by a palladium catalysis is described. A triarylphosphine-ligated palladium catalyst, which is capable of cleaving benzylic C–N bonds, realized facile dearomative reactions with C4 selectivity. Combined with precedented C2- and C3-selective functionalizations of benzyl amine derivatives, the present reaction can provide a new synthetic option for the synthesis of multi-substituted alicyclic compounds as well as aromatic compounds.
