Synthesis of optically active homotryptophan and its oxygen and sulfur analogues

Goswami, K.; Paul, S.; Bugde, S.T.; Sinha, S. (Tetrahedron. 68(1); 2012; 280-286.)

D-Homotryptophan and its sulfur analogue have been synthesized by Sonogashira coupling between 3-iodoheteroarenes and ethynyloxazolidine followed by reduction of triple bond and oxidation of alcohol to acid. L-Homotryptophan ...
Synthesis and thermal studies of the cobalt zinc ferrous fumarato-hydrazinate a precursor to obtain nanosize ferrites

Gonsalves, L.R.; Verenkar, V.M.S. (Journal of Thermal Analysis and Calorimetry. 108(3); 2012; 871-875.)

Nanosize Co1-x Zn(x)Fe2O4 (x = 0, 0.1, 0.3, and 0.4) have been synthesized by the precursor combustion technique via autocatalytic combustion of the mixed-metal fumarato-hydrazinate precursors. A key feature of these ...
Biogenetic-type synthesis of 2-hydroxy-4,4,7-trimethyl-1(4h)-naphthalenone, a modified apocarotenoid from Ipomoea pes-caprae

Fondekar, K.P.P.; Paknikar, S.K.; Torres, S.; Kamat, S.P. (Natural Product Communications. 7(7); 2012; 827-830.)

A biogenetic-type synthesis of 2-hydroxy-4,4,7-trimethyl-1(4H)-naphthalenone (1), a modified apocarotenoid isolated from Ipomoea pes-caprae (Linn.) R.Br. showing anti-inflammatory activity by inhibiting prostaglandin ...
Synthesis of Bis(indolyl)methanes under catalyst-free and solvent-free conditions

Dhumaskar, K.L.; Tilve, S.G. (Green Chemistry Letters and Reviews. 5(3); 2012; 353-402.)

Condensation of indole with aromatic aldehydes has been carried out without using any catalyst and solvent to give bis(indolyl)methanes.
Synthesis and characterization of ultrafine spinel ferrite obtained by precursor combustion technique

Gonsalves, L.R.; Mojumdar, S.C.; Verenkar, V.M.S. (Journal of Thermal Analysis and Calorimetry. 108(3); 2012; 859-863.)

Nanoparticles of the spinel ferrite, Co0.6Ni0.4Fe2O4 have been synthesized by the precursor combustion technique. This synthetic route makes use of a novel precursor viz., metal fumarato hydrazinate which decomposes ...
Synthesis and characterization of nanosize nickel-doped cobalt ferrite obtained by precursor combustion method

Gonsalves, L.R.; Verenkar, V.M.S. (Journal of Thermal Analysis and Calorimetry. 108(3); 2012; 877-880.)

Nanoparticles of the spinel ferrite, Co1-x Ni(x)Fe2O4 (x = 0, 0.2, 0.3) have been synthesized by the precursor combustion technique. Novel precursors of metal fumarato-hydrazinate have been employed to yield the nanosized ...
Synthesis, purification and thermal behaviour of sulfonated metalloporphyrins

Gokakakar, S.D.; Salker, A.V. (Journal of Thermal Analysis and Calorimetry. 109(3); 2012; 1487-1492.)

A free-base tetra sodium meso-tetra (p-sulphonatophenyl) porphyrin (TPPS4) and its corresponding metalloporphyrins (MTPPS4), where M = Co, Ni and Zn were synthesized and characterized by UV-visible spectroscopy, infra red ...
Nano-crystalline Mn sub(0.3) Ni sub(0.3) Zn sub(0.4) Fe sub(2) O sub(4) obtained by novel fumarato-hydrazinate precursor method

Gawas, U.B.; Verenkar, V.M.S.; Mojumdar, S.C. (Journal of Thermal Analysis and Calorimetry. 108(3); 2012; 865-870.)

Carboxylate hydrazinate complex involving mixed metals have been synthesized and used as precursor for preparing the nanocrystalline Mn-Ni-Zn ferrite. Chemical composition of complex was fixed from chemical analysis results, ...
Enhanced ionic conductivity in an otherwise poorly conducting Ce(0.90)Ca(0.10)O(2-delta) system

Banerjee, S.; Priolkar, K.R.; SujataDevi, P. (Inorganic Chemistry. 50(3); 2011; 711-713.)

A poorly conducting ionic material Ce(0.90)Ca(0.10)O(2-delta) was converted to a highly conducting composition by a codoping strategy with Sm3+ and Gd3+. A 50 precent replacement of Ca with either Sm or Gd has increased ...
Synthesis, properties and supramolecular structure of piperazinediium thiosulfate monohydrate

Srinivasan, B.R.; Naik, A.R.; Dhuri, S.N.; Naether, C.; Bensch, W. (Journal of Chemical Sciences. 123(1); 2011; 55-61.)

Aqueous reaction of ammonium thiosulfate with piperazine (pip) results in the formation of the title compound (pipH(2))[S2O3].H2O 1 (pipH(2) = piperazinediium) in good yield. 1 was characterized by elemental analysis, IR. ...
