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.
متن کاملSynthesis of tetra-substituted phenanthroimidazole derivatives using SBA-Pr-SO3H
A one pot four-component reaction of 9,10-phenanthraquinone, aromatic aldehyde, aniline, and ammonium acetate was designed for the preparation of tetrasubstituted imidazoles (phenanthro[9,10-d]imidazole) derivatives in the presence of SBA-Pr-SO3H as a mesoporous solid acid catalyst. Phenanthro[9,10-d]imidazole derivatives were produced by the use of this technique in short reaction times and go...
متن کاملSynthesis of Substituted α-Trifluoromethyl Piperidinic Derivatives.
A comprehensive survey of pathways leading to the generation of α-trifluoromethyl monocyclic piperidinic derivatives is provided (65 references). These compounds have been synthesized either from 6-membered rings e.g., pipecolic acid or lactam derivatives by introduction a trifluoromethyl group, from pyridine or pyridinone derivatives by reduction, and from 5-membered rings e.g., prolinol deriv...
متن کاملSynthesis of 1, 3-diaryl Substituted Iodobenzene Derivatives
The synthesis and characterization a new derivatives of 2'-iodo-meta terphenyl from the reaction ofexcess aryl-Grignard and 2, 6- dichloroiodobenzene with quenching of m-terphenyl-2'-magnesiumbromide by iodine is reported. Via the reactions three carbon-carbon bonds are constructed and mterphenylsare obtained in good yields.
متن کاملAminothiazolylglycyl derivatives of carbacephems. I. Synthesis and antibacterial activity of novel carbacephems with substituted aminothiazolyl groups.
A series of new carbacephem compounds which have substituted aminothiazolylglycyl side chain have been prepared starting from corresponding carbacephems with aminothiazolylmethoxyimino group. Among them, the compound having 3,4-dihydroxybenzoyl group showed very sharp activity against Pseudomonas aeruginosa. Moreover, the optical resolution of alpha carbon of aminothiazolylglycyl moiety was car...
