Abstract

Abstract Some Diels-Alder adducts of 1, 2, 4-trichloro-3, 5, 5-trimethoxycyclopentadiene were prepared and their structure elaborated by chemical transformations. By this it was established that a preferred formation of the 5-endo-substituted adducts is found for allyl bromide and allyl acetate, while acrolein yields an excess of the 6-endo-isomer.
