Synthesis of Peptidyl Ureas Using p‐Nitrophenyl‐(9‐fluorenylmethoxy Carbonylamino)methyl Carbamate Derivatives

Synthesis and properties of peptidyl derivatives of arginylfluoromethanes.

Two peptide derivatives of arginylfluoromethane (Arg-CH2F), namely Bz(benzoyl)-Phe-ArgCH2F and D-Phe-Pro-Arg-CH2F, have been synthesized by extension of available methods, i.e. the Dakin-West reaction [Rasnick (1985) Anal. Biochem. 149, 461-465] or synthesis of a phthaloyl-blocked C-terminal fluoromethane [Rauber, Angliker, Walker & Shaw (1986) Biochem. J. 239, 633-640; Angliker, Wikström, Raub...

synthesis of amido alkylnaphthols using nano-magnetic particles and surfactants

Novel Peptidyl Carbamate Inhibitors of the Enzyme Elastase

Mechanochemical synthesis of thioureas, ureas and guanidines

In this review, the recent progress in the synthesis of ureas, thioureas and guanidines by solid-state mechanochemical ball milling is highlighted. While the literature is abundant on their preparation in conventional solution environment, it was not until the advent of solvent-free manual grinding using a mortar and pestle and automated ball milling that new synthetic opportunities have opened...

single-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
