✦ Synopsis

Stereoselective Synthesis of a Bicyclic Ketooxetane via a Thionium Ion-Mediated Cyclization Reaction.

-Et-AlCl2-mediated cyclization of the Z-silyl enol ether onto the thionium ion trigger attached to the five-membered carbocyclic ring gives a good yield the desired bicyclic oxetane (II). It can be easily desulfurized with concomitant carbonyl reduction to the compound (III). Attempted cyclization of the six-membered substrate (IV) produces mainly products of a 1,2-hydride shift. -(CRAIG, D.; LAWRENCE,
