Derivatives of thiazolidinone ring systems are known to act as anti-HIV infections , analgesic, anti-bacterial, anti-convulsant, anti parasitic, potential anti-inflammatory and herbicidal agents. Due biological activities of thiazolidinones ring, several methods for their synthesis have been illustrated in literature. Imidazolidine-2-thiones were synthesized by the oxidative cyclization of 1-be...
متن کاملInfluence of the incorporation of a cyclohexenyl nucleic acid (CeNA) residue onto the sequence d(CGCGAATTCGCG)
Cyclohexene nucleic acids (CeNA), which are characterized by the presence of a cyclohexene moiety instead of a natural (deoxy)ribose sugar, are known to increase the thermal and enzymatic stability when incorporated in RNA oligonucleotides. As it has been demonstrated that even a single cyclohexenyl nucleoside, when incorporated in an oligonucleotide, can have a profound effect on the biologica...
متن کاملAmphiphilic allylation of arylidene-1,3-oxazol-5(4H)-one using bis-π-allylpalladium complexes: an approach to synthesis of cyclohexyl and cyclohexenyl α-amino acids.
An efficient method for synthesis of cyclohexyl and cyclohexenyl α-amino acids via palladium-catalyzed three-component assemblies followed by ring-closing metathesis (RCM) is described. The present catalytic reaction is successfully extended to substituted benzylidene azlactones 2a-j RCH=(1,3-oxazole): R = alkyl or aryl. The amphiphilic bis-allylation of these substrates has been achieved by re...
