Using a solution of a metal salt, it was possible to decrease the quantity of Ac2O used in the thiiranation of 2 ́-adamantylidene-9-benzonorbornenylidene 1 with 4,4 ́-dithiodimorpholine 4 and Ac2O. Thiiranation in a 0.1 M Et2O solution of LiClO4 at -15 °C afforded thiiranes 2 and 3 in moderate yields without the decomposition of the thermally less stable 3. © 2009 The Japan Institute of Heterocyclic Chemistry All rights reserved.
