## Abstract Novel C~2~‐symmetrical chiral sulfides were synthesized from (__R,R__)‐tartaric acid and their utility in the asymmetric epoxidation of aldehydes with benzyl bromide was examined. Among the sulfides used, silyl ether‐type sulfides were found to be superior to diol‐ and benzyl ether‐type

## Abstract Reactions of aromatic aldehydes with benzyl bromide or iodide in the presence of a catalytic amount (10 mol%) of a C~2~ symmetric sulfide having a binaphthyl skeleton afford the corresponding trans‐stilbene oxides in moderate to good yields with moderate enantioselectivities (up to 55%
