Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A nitrone is the N-oxide of an imine and a functional group in organic chemistry. The general structure is R1R2C=NR3+O- where R3 is different from H.A nitrone is 1,3-dipole in 1,3-dipolar cycloadditions. It reacts with alkenes to an isoxazolidine:One example of this reaction type is the reaction of various Baylis-Hillman adducts with C-Phenyl-N-methylnitrone forming an isoxazolidine in which R1 is phenyl, R2 is hydrogen and R3 is a methyl group .Nitrones react with terminal alkynes and a copper salt to beta-lactam. This reaction is also called the The Kinugasa reactionThe first step in this reaction is a dipolar cycloaddition of the nitrone with the in situ generated copper(I) acetylide to a 5-membered ring structure which rearranges in the second step.
