A concise total synthesis 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.
