## Abstract A short and facile synthesis of a series of 1, 2‐dihydroquiazolin‐4(3H)‐ones was accomplished in good yields via novel reductive cyclization of o‐nitrobenzamides with ketones promoted by TiCl~4~/Zn system. The structure was established on the basis of elemental analysis, IR, 'H NMR and

Low-Valent Titanium Induced Novel Reductive Cyclizations of Ξ±,Ξ²-Unsaturated Nitrile Compounds. -Cyclopentenes such as (II), (IV), and (VII) are easily prepared by cyclodimerization of Ξ±,Ξ²-unsaturated nitriles promoted by low-valent titanium reagent. Using the same reagent for nitro-compounds such a
