A new method for the synthesis of chiral 5,7-fused oxygen bridged ring based on Prins cyclization is reported. It provides a new way for the synthesis of the skeleton structure of guaiacane sesquiterpenes. Based on dioxinone, the synthesis of chiral 5,7-fused oxygen bridged ring is achieved in a two-step combined yield of 72% by using Lewis acid induced intra- molecular Prins cyclization.

Result

Key words: guaiane, chiral oxygen bridge seven-membered ring, Prins reaction
