A highly efficient and stereoselective synthesis of coumarin-, 1,3-cyclohexanedione-, and 1,4-naphthoquinone-fused 2,8-dioxabicyclo[3.3.1]nonanes is described. This was achieved via a sequential Michael addition/bicyclization reaction from easily accessible 3-(2-hydroxyphenyl)-1-phenylprop-2-en-1-one derivatives. Three chemical bonds (one C–C bond and two C–O bonds), two six-membered cycles, and two
描述了香豆素-,1,3-环己二酮-和1,4-萘醌稠合的2,8-二氧杂双环[3.3.1]壬烷的高效和立体选择性合成。这是通过从容易获得的3-(2-羟苯基)-1-苯基丙-2-烯-1-酮衍生物通过顺序迈克尔加成/二环化反应实现的。一锅操作中形成了三个化学键(一个C–C键和两个C–O键),两个六元循环和两个立体中心。
