Condensation of glyoxal with 2-aminobenzylamine produces the novel com
pound 2,2'-bi(1,2,3,4-tetrahydroquinazoline), 6, the structure of whic
h has been confirmed by X-ray crystallography. However, reaction of gl
yoxal with other 2-substituted benzylamines yields hexabenzylhexaazais
owurtzitanes. The crystal structure of the derivative prepared from 2-
methylbenzylamine has been determined and is compared with that of the
derivative from 4-chlorobenzylamine
