چکیده
The highly symmetric 13-aza-4,4,8,8,12,12-hexamethyl-2,6,10-trioxatricyclo[7,3,l,0513]tridecane is of general interest regarding several aspects. First, the molecule belongs to the rare point group C3. Second it is being discussed as a possible complexing agent [1]. Furthermore the title compound is quite inert against some drastic reaction con ditions, e.g. it does not react with lithium alu minium hydride in refluxing ether during four hours [2]. Starting in the 1950’s, the first synthesis of 13-aza-4,4,8,8,12,12-hexamethyl-2,6,10-trioxatricyclo[7,3,l,05’13]tridecane included 3-hydroxy2,2-dimethyl-propionaldehyde as one of the start ing materials [3, 2], Hasek and Martin isolated III by destructive distillation of the self-condensation product IV after removal of formaldehyde, isobutyraldehyde and other volatile products [4] (see
