[Figure not available: see fulltext.] This work shows for the first time the use of tetrakis(hydroxymethyl)glycoluril in the melt N-methylenation reactions of arylamines, based on the ability of tetrakis(hydroxymethyl)glycoluril to eliminate a formaldehyd

Bis(arylamino)methanes 4 free of amine contamination have been efficiently synthesized from N,O-acetals 1 following three different methodologies.The first two are useful for symmetrical aminals and involve the decomposition of an N,O-acetal by a base (ph
TRINUCLEAR INTERMEDIATES IN ANILINE-FORMALDEHYDE CONDENSATION

The trinuclear intermediate products 4-(4-anilinomethylanilinomethyl)aniline and 4-aniline were isolated and identified by TLC during investigation of the aniline-formaldehyde condensation in the presence of acidic catalysts.The transformation of these compounds and of 4-anilinomethylaniline in methanol and under the conditions of acid aniline-formaldehyde condensation and rearrangement are described.It was established that the fromation of polyamines is possible not only as a result of the initial reaction of the final diamines with formaldehyde but also of the reaction of protonated anilinomethylanilines with aromatic amines present in the reaction mixture.

Irradiation (1) (253-7 nm) of Na,Nb-dimethyltryptaimne with pyridine N-oxide or benzo[c]cinnoline N-oxide in CH2Cl2 yielded 1,8-dimethyl-3a-hydroxy-1,2,3,3a,8-8a,- hexahydropyrrolo[2,3-b]indole (19), while with visible light Nb-(4-cyanobutadienyl)-Na,Nb,- dimethyltryptamine (21) was obtained. This method was applied to trimethyltryptamine and the corresponding oxindole (34) and the N-formyl derivative (20) were obtained.
