Intercalation is one of the most important ways by which small molecules can interact with DNA. This timely analysis addresses a very important question: In the absence of a crystal structure, what constitutes strong experimental evidence for intercalative interactions?

Asymmetric aldol reactions promoted by organotin Lewis acids and chiral diamines previously could be conducted only on a stoichiometric basis. However, with appropriate modifications, this reaction can be rendered catalytic in both the organotin reagent and the chiral diamine. The result is a very powerful method for the synthesis of optically active syn aldol adducts.
