Structure - Catalytic Properties Relationship of New Macrocyclic Bisoxazolines

As a result of our research on catalyst for stereoselective cyclopropanation, we prepared macrocyclic bisoxazolines 1, the first examples of of new class of cavity-containing organometallic supramolecular catalysts. Some members of this group of compounds exhibited one of the highest diastereoselectivities (86% de) obtained to date in the cyclopropanation of styrene with ethyl diazoacetate.
