Dipolar Cycloadditions of Nitrones in Aqueous Media

HETEROCYCLES, 2016
1,3-Dipolar cycloadditions of nitrones in aqueous media have been recently exploited as a non-conventional protocol in the synthesis of the fully- or partly-saturated isoxazole ring. Water as the reaction medium can affect positively both cycloaddition rates and yields, while the large array of latent functionalities displayed by the cycloadducts is of

Concertedness of 1,3-dipolar cycloadditions

Journal of Chemical Education, 1984
The 1,3-dipolar cycloaddition is the union of a 1,3-dipole with a multiple bond system (a dipolarophile) to form a five-membered ring; the process is regarded as one of the most general methods for the synthesis of five-membered heterocycles.
