Abstract
The intramolecular [2 + 2]-photocycloaddition of the 1,3-divinyl-2-cyclopentyl tetronates 1 was performed under various conditions to give perfect diastereoselectivity and a regioselectivity of up to 85/15 in the presence of γ-cyclodextrin by differentiating the two chemically very similar double bonds of 1.Keywords
