Quantitative characterization of the global electrophilicity pattern of some reagents involved in 1,3-dipolar cycloaddition reactions
(Elsevier, 2003)
The global electrophilicity power, ω, of a series of dipoles and dipolarophiles commonly used in 1,3-dipolar cycloadditions may be conveniently classified within a unique relative scale. The effects of chemical substitution ...
1,3-dipolar cycloadditions of the versatile intermediate tetraethyl vinylidenebisphosphonate
(Georg Thieme Verlag Kg, 2013-09)
The use of tetraethyl vinylidenebisphosphonate as a dipolarophile in 1,3-dipolar cycloaddition reactions was investigated. In particular, the cycloaddition reactions between tetraethyl vinylidenebisphosphonate and azides ...
Asymmetric construction of substituted pyrrolidines via 1,3-dipolar cycloaddition of azomethine ylides and chiral acrylates derived from biomass
(ElsevierAmsterdam, 2014-04)
The first application of chiral auxiliaries synthesized from levoglucosenone (a biomass-derived anhydrosugar) in asymmetric 1,3-dipolar cycloaddition reactions of azomethine ylides is herein reported. The corresponding ...
1,3-Dipolar cycloaddition of nitrile imines with alpha,beta-unsaturated lactones, thiolactones and lactams: synthesis of ring-fused pyrazoles
(PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2012)
Application of copper(I)-catalysed azide/alkyne cycloaddition (CuAAC) `click chemistry` in carbohydrate drug and neoglycopolymer synthesis

Intramolecular azide-alkene cycloaddition-elimination reaction in an aldohex-2-enonic acid derivative
(Elsevier, 2019-09)
A 6-azido-2-tosylenolate, obtained from D-glucono-1,5-lactone in six steps, underwent an intramolecular cycloaddition–elimination pathway under mild conditions, yielding a chiral, substituted 5,6-dihydro-4H-pyrrolo ...
Stereospecific Synthesis of Pyrrolidines with Varied Configurations via 1,3-Dipolar Cycloadditions to Sugar-Derived Enones
(American Chemical Society, 2014-05)
Enantiomerically pure pyrrolidines have been obtained by 1,3-dipolar cycloaddition of stabilized azomethine ylides and sugar enones (dihydropyranones) derived from pentoses. Thus, the S-enone (menthyl 3,4-dideoxy-(1S)-pe ...
Microwave-assisted 1,3-dipolar cycloaddition of azomethine ylides to [60]fullerene: thermodynamic control of bis-addition with ionic liquids additives
(Wiley VCH Verlag, 2021-07)
The cycloaddition of azomethine ylides to [60]fullerene (C60) has been studied in ortho-dichlorobenzene (o-DCB) by evaluating the impact of an ionic liquid (IL) additive. The solvent effect has been addressed by evaluating ...
Unsupported Copper Nanoparticles in the 1,3-Dipolar Cycloaddition of Terminal Alkynes and Azides
(Wiley VCH Verlag, 2010-04)
Readily prepared copper nanoparticles were found to catalyse the 1,3-dipolar cycloaddition of azides and alkynes up to rates comparable to those of microwave chemistry. Both the preparation of the nanoparticles and the ...
Synthesis of pharmacophores containing a prolinate core using a multicomponent 1,3-dipolar cycloaddition of azomethine ylides
(Pergamon-Elsevier Science Ltd, 2017-12-07)
A multicomponent 1,3-dipolar cycloaddition between heterocyclic aldehydes, amino esters and dipolarophiles is efficiently promoted by silver acetate as catalyst, and depending on the nature of the heterocycle and its ...
