A concise totalsynthesis of (±)-pestalachloride C and (±)-pestalachloride D was achieved through a Knoevenagel/hetero-Diels–Alder cascade reaction to test the nonenzymatic biosynthetic hypothesis of Shao, Wang, and co-workers. The cascade reaction generates a mixture of racemic indano[2,1-c]chromans like those found in the natural products.
通过Knoevenagel / hetero-Diels-Alder级联反应测试Shao,Wang及其同事的非酶生物合成假说,可以简明地合成(±)-杀虫双酚C和(±)-杀虫双酚D。级联反应生成外消旋的茚并[2,1- c ]吡喃混合物,类似于天然产物中的混合物。
