Synthesis of oleophilic electron-rich phenylhydrazines
Phenylhydrazines 1 substituted with two or three long-chain alkyl, alkoxy or alkylsulfanyl groups were successfully prepared by acid-induced removal of the Boc group in hydrazides 2. The reaction is carried out with 5 equivalents of TfOH in CF(3)CH(2)OH/CH(2)Cl(2) at -40 °C for 1.5 min. Under these conditions, the deprotected hydrazine 1 is fully protonated, which increases its stability in the...
متن کاملTellurium in Organic Synthesis, IX [15] Oxidation of Some Nitrogenous Compounds with Te02
The reaction between bis(p-methoxyphenyl)telluroxide and various substituted phenylhydrazines has recently been reported [1]. In this reaction the phenylhydrazines are converted to the corresponding hydrocarbons and nitrogen, also producing bis(p-methoxyphenyl)telluride and an unsymmetrical telluride, resulting form aryl exchange. As a part of our investigation of the reactions of tellurium dio...
متن کاملSynthesis and Site-Specific Incorporation of Red-Shifted Azobenzene Amino Acids into Proteins
A series of red-shifted azobenzene amino acids were synthesized in moderate-to-excellent yields via a two-step procedure in which tyrosine derivatives were first oxidized to the corresponding quinonoidal spirolactones followed by ceric ammonium nitrate-catalyzed azo formation with the substituted phenylhydrazines. The resulting azobenzene-alanine derivatives exhibited efficient trans/cis photos...
متن کاملA Quantitative Color Reaction for Cortisone and Related 17,21-dihydroxy-20-ketosteroids By
The numerous combinations of functional groups occurring in the steroid hormones render difficult the development of a specific test for individual compounds. However, reactions which reveal certain groupings are available and may be applied singly or in combination to elucidate the characteristics of pure steroids or of compounds in a mixture. The ketol side chain, located at carbon atom 17 in...
متن کاملThe Chemoselective Fischer’s Synthesis of Indolenine Derivatives By iso-Butyric Acid As A Weak Organic Acid Catalyst
Iso-butyric acid as a new, simple, and expensive solvent/catalyst was successfully used for the chemoselective Fischer’s synthesis of indolenines derivatives 3a-r by one-pot condensation reaction of various phenylhydrazines 1a-e with the substituted acetophenones 2a-c at reflux conditions. In this protocol, all products 3a-r were obtained in high yields and short reaction time. The structures o...
