Singh, Bara published the artcilePd-Catalyzed Nazarov-Type Cyclization: Application in the Total Synthesis of β-Diasarone and Other Complex Cyclopentanoids, Synthetic Route of 91-16-7, the publication is Organic Letters (2022), 24(4), 1043-1048, database is CAplus and MEDLINE.
Author describe the palladium-catalyzed Nazarov-type cyclization of easily accessible (hetero)arylallyl acetates to pentannulated (hetero)arenes. This method provides ready access to various types of bi-, tri-, tetra-, and pentacyclic cyclopentanoids under neutral conditions. The synthetic utility is further demonstrated in the first total synthesis of β-diasarone (I) and several other complex cyclopentanoids relevant to medicinal chem. and materials science.
