The reaction of harmine with phenacyl bromides or ethyl bromoacetate gives quaternized harmine derivatives. The cyclization of the phenacylharminium salts yields the corresponding 2-aryl-11H-indolizino[8,7-b]indoles. Vilsmaier-Haack formylation of 11H-indolizino[8,7-b]indoles leads to the corresponding 3,10-bisformyl derivatives. The acylation proceeds selectively at C(3) to give 3‑acetyl-2‑aryl-11H-indolizino[8,7-b]indole.
