摘要：

The structures and stereochemistry of the major Diels-Alder adducts of 1,3-dimethyl-1,3-cyclohexadiene (2) with methyl vinyl ketone, methyl acrylate, and ethyl propiolate have been established as 4a, 4b, and 6d, respectively. Lactonization of acid 4c afforded either novel δ-lactone 7 or γ-lactone 8 as the major product depending on the conditions used. Lactone 7, the kinetically stable product, represents the first of such δ-lac-tones to be isolated in the bicyclo[2.2.2]octane series. © 1969, American Chemical Society. All rights reserved.
