Site selectivity, regioselectivity, and stereoselectivity of [2 + 3] cycloaddition of benzonitrile oxides to polyunsaturated esters were examined. Site selectivity was correlated with electron charges of unsaturated carbon atoms. Structure of the products has been established by an extensive application of 1H and 13C NMR spectroscopy and electrospray ionization mass spectrometry.Graphical abstract

Unexpected course of reaction between (E)-2-aryl-1-cyano-1-nitroethenes and diazafluorene: why is there no 1,3-dipolar cycloaddition?

Reactions between (E)-2-aryl-1-cyano-1-nitroethenes and diazafluorene lead to acyclic 2,3-diazabuta-1,3-diene derivatives, instead of the expected pyrazoline systems. DFT calculations suggest that



NMR Studies on [2 + 3] Cycloaddition of Nitrile Oxides to Polyunsaturated Medium Size Rings

Site selectivity, regioselectivity and stereoselectivity of [2 + 3] cycloaddition of 4-trifluoromethylbenzonitrile oxide to polyunsaturated medium size rings including 1,5,9-cyclododecatriene,

NMR studies on 1,3-dipolar cycloaddition of nitrile oxides to norbornenes

The 1,3-dipolar cycloaddition reaction of nitrile oxides to norbornenes substituted with an acrylate-derived moiety was examined. Only adducts to norbornene system were formed with a good exo

Asymmetric 1,3-Dipolar Cycloadditions

This review is intended to update the recent developments in asymmetric 1,3-dipolar cycloaddition reactions involving a variety of heteroylides (or ylide equivalents) and dipolarophiles, covering the

Application of chiral ligands: carbohydrates, alkaloids–lanthanides and other Lewis acid complexes to control regio- and stereoselectivity of the dipolar cycloaddition reactions of nitrile oxides and crotonamides and cinnamides

Chiral Lewis acid mediated 1,3-dipolar cycloaddition reactions of aryl nitrile oxides and secondary α- or β-substituted acrylamides and cinnamides were examined. Excellent enantioselectivities with

Derivatives of tetrahydro-2 H -pyridine from photorearranged cycloadducts of nitrile oxides

A Convenient Preparative Method of Nitrile Oxides by the Dehydration of Primary Nitro Compounds with Ethyl Chloroformate or Benzenesulfonyl Chloride in the Presence of Triethylamine

Three nitrile oxides (MeOCOC≡N→O, PhC≡N→O, and EtC≡N→O) were effectively generated in situ by dehydration of the corresponding primary nitro compounds (RCH2NO2) with PhSO2Cl or ClCOOEt in the

A divergent approach to the myriaporones and tedanolide: completion of the carbon skeleton of myriaporone 1.

A linear but concise synthetic approach toward the structurally related natural products myriaporone and tedanolide is reported, highlighted by a stereoselective homoallenylboration and a regio- and chemoselectives nitrile oxide cycloaddition.

1,3-Dipolar Cycloaddition to Tricarbonyl[(1−4-η)-2- methoxy-5-methylenecyclohexa-1,3-diene]iron: Rapid Construction of a Spiro[4.5]decane System

Tricarbonyl[(1−4-η)-2-methoxy-5-methylenecyclohexa-1,3-diene]iron (1) undergoes 1,3-dipolar cycloaddition reaction regio-, stereo-, and chemoselectively at its exocyclic double bond, yielding a
