The condensation of aniline with glyoxal and formaldehyde in stoichiometric ratio, leads to 2,4,6,8-tetraphenyl-2,4,6,8-tetraazabicyclol3.3.0]octane (lf) with formic acid as catalyst. Nine substituted derivatives of If have been prepared in high yield by this synthetic method. X-ray analysis reveale
