Several 1,3-dienic terpenes of various structural types are attacked by the title dienophile from the less hindered side. The regiospecificity of attack by methyl triazolinedione(MTAD), 1, upon 1,3-conjugated dienes belonging to the [2.2.2Jbicyclooctane or the norbornane families has been shown to o
## Abstract The title dienophiles attack nopadiene from the less hindered side.
The nonconjugated bicyclo[3.2.l]octa-2,6-diene (1) affords with 4-methyl-1,2,4-triazolin-3,5-dione (MTAD) the homo-cycloadduct (2) product and the rearranged urazoles ( 2) and ( 2) through dipolar cycloaddition, while ene-reaction and (2+2)-cycloaddition are not observed. Bicyclo[3.2.l]octa-2,6-die
