The title compound 4, prepared by lead tetraacetate oxidation of 5, is stable at room temperature and aziridinates alkenes in better yield and higher diastereoselectivity than, e.g. the 2-ethyl compound 1; hydrazinolysis of the quinazolinone ring in 20 gives the corresponding N-aminoaziridine 21 in 64% yield.
Nanofilms useful for filtration are prepared from oriented amphiphilic molecules and oriented macrocyclic modules. The amphiphilic species may be oriented on an interface or surface. The nanofilm may be prepared by depositing or attaching an oriented layer to a substrate. A nanofilm may also be prepared by coupling the oriented macrocyclic modules to provide a membrane.
