The cycloaddition of C,N-diphenyl- and C-benzoyl-N-phenylnitrones to 2-Alkoxy-1,3-alkadienes leads to 5-substituted isoxazolidines.Irrespective of the substituent at the C atom of the nitrone, the structure of the alkoxyl radical of the dipolarophile, and the reaction conditions, the addition of the nitrones to 2-substituted dienyl ethers only takes place at the unsubstituted double bond.In the case of 2-isopropoxy- and 2-tert-butoxy-1,3-butadienes a mixture of diastereomers is formed.
