The [4 + 2] cycloaddition stereoselectivity of dienamines 1–4 with dimethyl fumarate and fumaronitrile has been investigated, and functionalised decalins 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.
已经研究了二烯胺1–4与富马酸二甲酯和富马腈的[4 + 2]环加成立体选择性,并通过从环加合物7-11和15-20中消除Me 2 NH来制备官能化的十氢化萘21-40。在合成树烯倍半萜的背景下,还描述了二二酯29和30的还原。
