## Abstract The domino “[3+3] cyclization–ring‐opening” reactions of 1,3‐bis(trimethylsilyloxy)‐1,3‐butadienes with 3‐acetyl‐5‐vinyl‐4,5‐dihydrofurans afforded 5‐(4‐halobut‐2‐en‐1‐yl)salicylates. The reactions of 1,3‐bis(trimethylsilyloxy)‐1,3‐butadienes with 3‐acetyl‐5‐aryl‐4,5‐dihydrofurans gave
## Abstract The reaction of 1,3‐bis(trimethylsilyloxy)‐1,3‐butadienes with 3‐benzoyl‐5‐aryl‐4,5‐dihydrofurans, available by CAN‐mediated reaction of styrenes with benzoylacetones, afforded functionalized 9,10‐dihydrophenanthrenes. These reactions proceed by a novel domino [3+3] cyclization/ring‐ope
