Since the quinazoline and its derivatives have been considered as a novel class of cancer chemotherapeutic agents that show promising activity against different tumors, a new series of 6-iodo-2-undecylquinazolin-4(3H)-ones were prepared via reaction of 6-iodo-2-undecyl-4H-benzoxazin-4-one with nitrogen nucleophiles, namely, primary amines, 4-amino antipyrine, hydrazine hydrate, diamines, ethanol amine, and/or hydrazide derivatives and screened for their antitumor activity in vitro against a panel of three human tumor cell lines namely; hepatocellular carcinoma (liver) HepG2, colon cancer HCT-116, and mammary gland breast MCF-7. Compounds 14, 16, and 18 showed remarkable broad spectrum antitumor activity. All compounds were fully characterized by means of IR, MS, and 1H-NMR spectra.

Solvent-free domino acylation/cyclization reactions between fatty acid esters and o-phenylenediamine mediated by immobilized lipase from Mucor miehei (MML) were found to be an efficient way in the synthesis of 2- alkylbenzimidazole. Compared with other substrates, methyl fatty acid esters with moderated chain length exhibited best activity with yield up to 95%. The mechanism of the domino process was clarified deeply through some detail experiments, including separation of intermediates. This efficient enzymatic domino process provides an attractive procedure for heterocyclic compound synthesis and could be regarded as a potential synthetic method in modern organic chemistry.
