摘要：

Successive [4 + 2] cycloadditions of dimethyl 1,2-cyclobutadienedicarboxylate (1), first with itself and then with the next highest adducts 2 and 3, result in the [7]-ladderane 4. The [n]-ladderanes 2-4 are of interest because of their weak sigma framework and the very different polarities of the two sides of the molecule. R = CO2Me.
