Construction of furo[3,4-c]pyran ring skeleton was achieved starting from the Baylis–Hillman adducts. The synthesis was carried out by the successive introduction of propargyl alcohol, radical cyclization, reduction, allylation, and finally ring-closing metathesis reaction.
从Baylis-Hillman加合物开始,实现了
呋喃[3,4- c ]
吡喃环骨架的构建。通过依次引入炔
丙醇,自由基环化,还原,烯丙基化以及最后的闭环易位反应来进行合成。
