Phytochemical investigations of Piper sarmentosum Roxb., yielded four compounds; three amides, identified as 3-(3’,4’,5’-trimethoxyphenylpropanoyl) pyrrolidine, 3-(4’-methoxyphenylpropanoyl) pyrrole, N -(3-phenylpropanoyl) pyrrole and a sterol namely β -sitosterol . 3-(4’-Methoxyphenylpropanoyl) pyrrole was found for the first time in this Piper spe...

The title nitro-pyrrole-based compounds, C7H8N2O4, (I) (ethyl 4-nitro-1H-pyrrole-2-carboxyl-ate), its derivative C12H14N2O4, (II) [ethyl 4-nitro-1-(4-pent-yn-yl)-1H-pyrrole-2-carboxyl-ate], C15H26N4O3, (III) {N-[3-(di-methyamino)prop-yl]-1-isopentyl-4-nitro-1H-pyrrole-2-carboxamide}, and C20H27N9O5, (IV) {1-(3-azido-prop-yl)-4-(1-methyl-4-nitro-1H-pyrrole-2-carboxamido)-N-[2-(morpholin-4-yl)eth...

Reaction of dialkyl acetylenedicarboxylates 1a-c andpyrrole derivatives 2a-e in the presence of triphenylphosphite (TPP) was investigated and the effect of the pyrrole substitution was established. Diastereoselectivity is observed with pyrroles, 2a,b, yieldingphosphonate ester derivatives 3a-f and 4,and their relative configuration is determined by 1H/13C and 31</...

Metal complexes of 2,5-dicarboxamidopyrroles and 2,5-dicarbothioamidopyrroles have been structurally characterised for the first time, complementing the significant amount of work that has been reported for the analogous pyridine ligands. N,N'-Bis(3,5-dinitrophenyl)-3,4-diphenyl-1H-pyrrole-2,5-dicarboxamide forms octahedral bis(tridentate) complexes with cobalt(III) and nickel(II), where the li...

The title compound, [Co(C(14)H(17)N(5))(C(6)H(7)N)](C(24)H(20)B) or [Co{(pyrrole)(2)dien}(4-Mepy)]BPh(4) where (pyrrole)(2)dien is 2,2'-[(3-aza-pentane-1,5-diylbis(nitrilo-methyl-idyne)]dipyrrole and 4-Mepy is 4-methyl-pyridine, contains a penta-dentate (pyrrole)(2)dien ligand furnishing an N(5) set, such that two of the pyrrole N atoms and two of the dien N atoms occupy the equatorial position...
