Facile synthesis of hydantoin/1,2,4-oxadiazoline spiro-compounds via 1,3-dipolar cycloaddition of nitrile oxides to 5-iminohydantoins [PDF]
Beilstein Journal of Organic ChemistryThe cycloaddition of 1,3-dipoles at C=N bonds is a relatively rare process, in contrast to the widespread cycloaddition reactions at C=C, C≡C, and C=S bonds.

1,3-Dipolar cycloadditions of acridine with nitrile oxides [PDF]
ARKIVOC, 2002 Siteand regio-isomeric mono-cycloadducts 9 are formed in the reactions of mesito1b and dichloromesitonitrile oxide 1c with acridine 6 in a 1:2 ratio, while the reaction of 1b and 6 in a 10:1 ratio afforded, besides the mono-cycloadduct 9b and traces of the corresponding oxime 10b, the bis-cycloadduct 12 with the opposite regiochemistry to that of the ...

Combined experimental and theoretical studies of regio- and stereoselectivity in reactions of β-isoxazolyl- and β-imidazolyl enamines with nitrile oxides [PDF]
Beilstein Journal of Organic Chemistry, 2016 Reactions of β-azolyl enamines and nitrile oxides were studied by both experimental and theoretical methods. (E)-β-(4-Nitroimidazol-5-yl), (5-nitroimidazol-4-yl) and isoxazol-5-yl enamines smoothly react regioselectively at room temperature in dioxane ...

Pharmacochemical Studies of Synthesized Coumarin–Isoxazole–Pyridine Hybrids [PDF]
MoleculesSeveral new coumarin–isoxazole–pyridine hybrids were synthesized through a 1,3-dipolar cycloaddition reaction of nitrile oxides, prepared in situ from pyridine aldehyde oximes, with propargyloxy- or propargylaminocoumarins in moderate-to-good yields ...
