title: Diastereoselective, titanium-mediated cyclization of omega-vinyl tethered imides.
abstract: [reaction: see text] Diastereoselective reductive coupling reactions of omega-vinyl tethered cyclic imides are achieved by a preexisting stereocenter at an allylic position. Particularly noteworthy is the effective use of a 1:2 mixture of Ti(O-i-Pr)4 and n-BuLi to afford the N-acylhemiaminal products in good yields.
