Abstract
The synthesis of the title compounds, consisting in the replacement of chlorine in commercial a-chlorodiazines and cyanuryl chloride by the 3,7-dioxa-r-1-azabicyclo[3.3.0]oct-c-5-ylmethoxy group (Williamson method) is described. The stereochemistry of this new series is analysed in terms of different conformational chirality exhibited in solution (1H DNMR) vs. solid state (X-Ray Diffractometry), meso against chiral forms respectively. In solid state, the inclusion capacity of some chiral networks as well as their supramolecular aggregation is pointed out.
