摘要
[2 + 4] Cycloadditions of the nitroisoxazoles 1 and 2 with 2,3-dimethylbuta-1,3-diene afforded the bicyclic derivatives 3 and 4 in good yields; the regio- and stereochemical pattern of the reactions of the same compounds with isoprene and cyclohexa-1,3-diene, respectively, was investigated. The structures of the new compounds were established on the basis of spectroscopic and chemical data. © 1990, American Chemical Society. All rights reserved.
