The [4 + 2] cycloadditionstereoselectivity of dienamines 1–4 with dimethyl fumarate and fumaronitrile has been investigated, and functionaliseddecalins 21–40 have been prepared by elimination of Me2NH from cycloadducts 7–11 and 15–20; in the context of the synthesis of drimane sesquiterpenes, the reduction of dienediesters 29 and 30 is also described.
