ChemInform Abstract: Polyazapolycyclics by Condensation of Aldehydes with Amines. Part 2. Formation of 2,4,6,8,10,12‐Hexabenzyl‐2,4,6,8,10,12‐hexaazatetracyclo‐(5.5.0.05,9.03,11)dodecanes from Glyoxal and Benzylamines.

Abstract Cyclocondensation reaction of the benzylic amines (I) with glyoxal (II) in the presence of formic acid is performed in aqueous acetonitrile or methanol to produce the hexaazaisowurtzitanes (V).
