A tandem bicyclization strategy has been developed for the stereoselective synthesis of 3,4‐dihydro‐2 H ,6 H ‐2,6‐methanobenzo[ b ][1,5]dioxocine derivatives in good yields and selectivities through the cyclocondensation of 2‐(1‐hydroxy‐3‐methylbut‐3‐en‐1‐yl)phenol with various aldehydes by using 10 mol % BF 3 ⋅ OEt 2 . This is the first reported stereoselective construction of a bridged tricyclic skeleton through a cascade Prins cyclization procedure. This process constitutes an elegant strategy for the quick construction of tricyclic architectures in a single step.
