Improved synthesis of N1-substituted orotic acid derivatives.

An improved method for the synthesis of N1-substituted orotic acid derivatives is reported. The method involves sequential incorporation of nitrogen atoms to the pyrimidine structure from simple starting materials and thus allows the synthesis of N1-substituted orotic acid derivatives with single 15N label at either N-1 or N-3.

Nano silica sulfuric acid catalyzed synthesis of 2-substituted aryl (indolyl) kojic acid derivatives

Nano silica sulfuric acid as a solid acid, was described to be an effective catalyst for one-pot three-component reaction of kojic acid, aryl aldehydes and indoles for the preparation of 2-substituted aryl (indolyl) kojic acid derivatives. The catalyst was prepared by combination of chlorosulfonic acid to nano silica gel. The size of nanoparticles were observed with SEM.All prepared compounds w...

Synthesis of N1-phenethyl substituted indole derivatives as new melatoninergic agonists and antagonists.

The potency of new indolic N1-phenethyl substituted melatoninergic ligands with and without methyl groups in the alpha and beta position of the alkanamidoethyl side chain was examined using the pigment aggregation response in a clonal line of Xenopus laevis melanophores. The non 5-OMe substituted compounds, 8a--e, are all weak antagonists while introduction of the 5-OMe group, 9a--e, increases ...

The Synthesis of Orotic Acid-C14O2H

Orotic acid-C1402H, which was required for biological studies being pursued in this laboratory, has been synthesized by the method of Nyc and Mitchell,5 starting with DL-aspartic acid-a-C1402H. The latter was prepared from ethyl malonate-C1402C2H5, as described by Galat.' This orotic acid probably contains the isotopic carbon exclusively in the carboxyl group since it evolves carbon dioxide con...
