## Abstract A short and facile synthesis of a series of 1, 2βdihydroquiazolinβ4(3H)βones was accomplished in good yields via novel reductive cyclization of oβnitrobenzamides with ketones promoted by TiCl~4~/Zn system. The structure was established on the basis of elemental analysis, IR, 'H NMR and
The titanium-mediated cyclization of d,o-enones by using dichlorotitanium diphenoxide-cyclohexylmagnesium chloride diastereoselectively afforded cis-substituted cyclopentanols and was thus found to parallel the stoichiometric and catalytic titanocene-mediated reactions.
