Baylis-Hillman reaction of dialdehydes with methyl acrylate, followed by acetylation of the resulting diols gave diacetates 3, 14, 16 and 20. Treated with ammonia, these diacetates afforded new cyclophanes and the corresponding macrobicyclic cryptophanes. Conformational analysis of the cyclophanes was described.
与丙烯酸甲酯二醛的的Baylis-Hillman反应,接着将得到的二元醇的乙酰化,得到二乙酸酯3,14,16和20。用氨处理后,这些二乙酸酯提供了新的环烷和相应的大双环隐烷。描述了环烷的构象分析。
