## Abstract The cycloadditions of methyl propynoate and methyl vinyl ketone to 5,6‐dimethylidene‐2‐norbornanone (**6**) are __para__′‐regioselective“Para” (__p__) designs in this paper the 4, 9‐disubstituted tricclo[6.2.1.0^2, 7^] undecane‐ and 4, 9‐disubsstituted tricycle[6.2.20^2,7^] dodecane der
## Abstract A short synthesis of the title compound **13** is reported. The acetal group in **13** enables one to control the regio‐ and stereoselectivity of the two successive __Diels__‐__Alder__ additions of the tetraene. The first addition is significantly faster than the second one, thus making
