Asymmetric epoxidation of aldehydes catalyzed by new C2-symmetrical chiral sulfide

Asymmetric synthesis of chiral epoxides from various aldehydes with benzyl bromide was investigated using new C2-symmetrical chiral sulfides, which were readily prepared from (R,R)-tartaric acid.

2-Alkenyl dioxolanylium cations, new reactive dienophiles in low temperature asymmetric Diels-Alder reactions

Chiral orthoesters 14-22 were prepared by an exchange reaction with orthoester 13. These compounds, after treatment with trimethylsilyltriflate or tin(IV) chloride, gave rise to vinyl dioxolanylium cations which proved to be very reactive dienophils in various Diels-Alder reactions.
