## Abstract The cycloadditions of 3‐(__p__‐toluenesulfonyl)‐2‐propenal with cyclopentadiene, 1,3‐cyclo‐hexadiene, 1‐methoxy‐1,3‐cyclohexadiene, 1‐(trimethylsilyloxy)‐1,3‐butadiene, or 1,3‐diphenyliso‐benzofuran have been easily carried out at room temperature in the absence of catalyst. In contrast
