In the presence of cesium carbonate, a variety of aldehydes can be epoxidized directly with ally1 bromide at 50Β°C under solid-liquid phase transfer condition by use of a catalytic amount of diisobutyl telluride to afford vinyl epoxides in good yields with predominant cis stereoselectivity.

Chiral tert-butylsulfinyl group has been shown to be the chiral auxiliary of choice for the asymmetric aziridination of N-sulfinyliminas. Moreover, the sense of the asymmetric induction can be tuned in two ways: the chirality at the tert-butylsulfinyl Sulfur, or the nature of the methylene transfer
