“…The synthesis of such molecules can either start from condensation reactions (mostly carbonyl compounds in aldol-like reactions), the cyclotrimerization reactions of alkynes (Reppe-type chemistry) [ 35 ], or by the functionalization of appropriately equipped building blocks of type A , such as triesters, triamines and trihalides [ 36 ] ( Figure 1 ).…”

A series of C3-symmetric fully substituted benzenes were prepared based on alkyl triamino-benzene-tricarboxylates. Starting with a one step-synthesis, the alkyl triamino-benzene-tricarboxylates were synthesized using the corresponding cyanoacetates. The reactivity of these electronically sophisticated compounds was investigated by the formation of azides, the click reaction of the azides and a Sandmeyer-like reaction. Caused by the low stability of triaminobenzenes, direct N-alkylation was rarely reported. The use of the stable alkyl triamino-benzene-tricarboxylates allowed us total N-alkylation under standard alkylation conditions. The molecular structures of the C3-symmetric structures have been corroborated by an X-ray analysis.
