We have this program called Essential Spartan and we have to do some calculations of the diels-alder reaction of furan and maleic anhydride. I'm having trouble drawing the products which are called only endo and exo adduct.

Anyone know what the names of the products are?

Has anyone used Essential Spartan?

Thanks

See e.g. http://dx.doi.org/10.1021/jo050759z for the two isomers.

As to the other part, I've used Spartan (but very briefly and some time ago)
