A facile synthesis of functionalized 7,8-diaza[5]helicenes through an oxidative ring-closure of 1,1'-binaphthalene- 2,2'-diamines (BINAMs)

A facile and moderately functional-group-tolerant synthetic method for the preparation of 7,8-diaza[5]helicenes has been developed. It comprises of an oxidative ring-closing process of 1,1'-binaphthalene-2,2'-diamine (BINAM) derivatives with a chlorinecontaining oxidant (t - BuOCl) in the presence of a base (2,6-lutidine). In addition the basic physicochemical properties of newly synthesized compounds have been investigated.

A simple approach for the synthesis of 7,8-diaza[5]helicene

An oxidative route for the formation of 7,8-diaza[5]helicene and the corresponding N-oxides in high yields was developed. A mechanism of formation and possible interconversion of these products is put forward. Reduction of the N-oxides provided the title compound in quantitative yield. Georg Thieme Verlag Stuttgart.
