Abstract
Acid-induced cyclization of polyprenoids is one of the simplest and most widely used methods for the synthesis of polycyclic terpenoids. 1 We recently reported the first enantioselective cyclization of 2-polyprenylphenols induced by a Lewis acidassisted chiral Brønsted acid (chiral LBA), 1. 2 A hydroxy group in polyprenylphenols assists this polyene cyclization as a good nucleophilic internal terminator. We describe here the application of ...
