Cycloaddition reactions of enoldiazo compounds
(Chemical Society Reviews;, 2017-07-20)
Enoldiazo esters and amides have proven to be versatile reagents for cycloaddition reactions that allow highly efficient construction of various carbocycles and heterocycles. Their versatility is exemplified by (1) ...
Chiral donor−acceptor azetines as powerful reactants for synthesis of amino acid derivatives
(Nature Communications;, 2019-11-22)
Coupling reactions of amines and alcohols are of central importance for applications in chemistry and biology. These transformations typically involve the use of a reagent, activated as an electrophile, onto which nucleophile ...
Vinyldiazo Reagents and Metal Catalysts: A Versatile Toolkit for Heterocycle and Carbocycle Construction
Over the past decade, vinyldiazo compounds have provided mild, efficient, and highly selective methods for the construction of heterocycles and carbocycles. Dinitrogen extrusion with suitable catalysts provides the carbon ...
Chemoselectivity in Dirhodium(II) Catalyzed Reactions of Diazoacetoacetates Prepared from α,β-Unsaturated Ketones
α-Diazo β-keto esters from zinc triflate catalyzed Mukaiyama-Michael reactions between α,β unsaturated ketones and α silyloxyvinyldiazoacetates are valuable synthons for the synthesis of compounds that can be accessed ...
Silver-Catalyzed Carbene Functionalization of Methane in Supercritical Carbon Dioxide
Highly selective acylation of polyamines and aminoglycosides by 5-acyl-5-phenyl-1,5-dihydro-4H-pyrazol-4-ones
(Chemical Science;, 2017-08-30)
5-Acyl-5-phenyl-1,5-dihydro-4H-pyrazol-4-ones, accessible from arylpropargyl phenyldiazoacetates, are highly selective acyl transfer reagents for di- and polyamines, as well as aminoalcohols and aminothiols. As reagents ...
