NovelN-transfer reagent for converting α-amino acid derivatives to α-diazo compounds

A novel universalN-transfer reagent for direct and effective transformation of α-amino ketones, acetamides, and esters to the corresponding α-diazo products under mild basic conditions has been developed. This one-step synthetic approach not only allows for generation of α-substituted-α-diazo carbonyl compounds from α-amino acid derivatives but also permits preparation of α-diazo dipeptides fromN-terminal dipeptides (32 examples, up to 91%).

Metal-Free Insertion Reactions of Diazo Carbonyls to Azlactones

Insertion reactions of diazo carbonyls to azlactones in basic conditions have been performed. The developed method allows the preparation of a wide range of oxazole derivatives in yields ranging from 74 to 98%. Different substituents on both azlactone rings and diazo carbonyls do not compromise the methodology, even those containing stereogenic centers. Isotopic labeling experiments revealed the mechanism may proceed through a rare diazo carbonyl activation by an ammonium salt derivative.

One-pot synthesis of trans-β-lactams from ferrocenylketene generated by thermal Wolff rearrangement

A series of β-lactams containing the ferrocene moiety were synthesized through the Staudinger reaction between ferrocenylketene generated by the thermal Wolff rearrangement of the corresponding diazo ketone and various imines. The stereochemical outcome h

Facile access to 2,2-disubstituted indolin-3-ones: Via a cascade Fischer indolization/Claisen rearrangement reaction

An efficient approach for the synthesis of 2,2-disubstituted indolin-3-ones is described. From readily accessible aryl hydrazines and allyloxyketones, 2,2-disubstituted indolin-3-ones could be obtained in good to excellent yields under mild reaction condi

An efficient PEG-400 mediated catalyst free green synthesis of 2-amino-thiazoles from α-diazoketones and thiourea

A simple and efficient method has been developed for the synthesis of 2-aminothiazoles from α-diazoketones using PEG-400 solvent system. This novel synthetic approach involves the reaction between thiourea and α-diazoketones in PEG-400 at 100 °C to yield the corresponding 2-aminothiazoles in good yields. The method is simple, rapid and generates thiazole derivatives in excellent yields without the use of any catalysts. This green protocol can be utilized for fast synthesis of various 2-aminothiazoles in good yields. [Figure not available: see fulltext.]

One-pot synthesis of polyfunctional pyrazoles: An easy access to α-diazoketones from arylglyoxal monohydrates and tosylhydrazine

A new and efficient method for the generation of α-diazoketones has been developed from arylglyoxal monohydrates and tosylhydrazine at room temperature. 1,3-Dipolar cycloaddition reactions were used to constructing polyfunctional pyrazole derivatives by the reaction of generated α-diazoketones in situ with electron-deficient alkenes, quinones and coumarins in one pot. The one-dimensional molecular packing of 1H-benzo[f]indazole-4,9-dione derivatives along the c direction demonstrated a helical chain formation via N-H?O hydrogen-bonding.

Amination of phenylketene revisit. Substituent effect on reactivity

A cascade approach to pyridines from 2-Azido-2,4-dienoates and α-diazocarbonyl compounds

A one-pot synthesis of substituted pyridines via a cascade reaction of 2-azido-2,4-dienoates with α-diazocarbonyl compounds and triphenylphosphine is reported. The process involves a Staudinger-Meyer reaction, a Wolff rearrangement, an aza-Wittig reaction, and an electrocyclic ring- closure. The procedure is general and efficient. The substrates are readily available.

First example of the coupling of α-diazoketones with thiourea: a novel route for the synthesis of 2-aminothiazoles

α-Diazoketones undergo smooth coupling with thiourea in the presence of 10 mol % of copper(II) triflate to produce the corresponding 2-aminothiazoles in excellent yields with high selectivity. The use of copper(II) triflate makes this method simple, convenient and practical. This method works well with both aryl and alkyl diazoketones to furnish a wide range of 2-aminothiazoles.

A new and efficient route toward the preparation of diazo ketones using cyanuric chloride and diazomethane

A new method for the preparation of diazo ketones has been developed. 2,4,6-Trichloro-1,3,5-triazine (cyanuric chloride) has been found to be an excellent coupling reagent allowing for the efficient transfer of diazomethane to a carboxylic acid. Preparation of diazo ketones using carboxylic acids and triazine reagents is considerably more convenient than classical diazo transfer protocols because water does not have to be stringently removed and the entire procedure can be carried out in one-pot. Electron deficient and neutral aryl carboxylic acids were found to give better results than electron rich or aliphatic carboxylic acids. (C) 2000 Elsevier Science Ltd.
