Diels-Alder Reaction - Does It Need a Catalyst?

[geo_alchemist]

does diels-alder reaction needs any kind of catalist. I know that some catalists are used in assimetric diels alder sinthesis, but I don't need it. I need only diels-alder reaction.

The reaction doesn't need a catalyst, but the structure of the reactants you are using can greatly effect your yield. Some dienes work well while others don't work well, if at all, and the same can be said for the dienophile).
