The inter- and intramolecular couplings of unactivated alkenes to 3,4-dihydroquinazolines with a Rh(I) catalyst are reported. Coupling between olefins and NH-3,4-dihydroquinazoline was found to occur consecutively with heterocycle dehydrogenation in the p

Bis-ortho-nitration of α-phenyl-N-(phenylmethyl)-γ-butanelactam (6) using acetyl nitrate followed by reduction and regiospecific dehydrative cyclization afforded quinazoline 12.The aniline moiety in 12 could be dimethylated by using aqueous formaldehyde a
