With sulfinyl and sulfonyl groups, a poorly stereoselective reaction wasobserved, whereas with a sulfanyl moiety, the diastereoselectivity can be high as 96:4. The role ofthe oxygen atom on the sulfur moiety is discussed." . . . "Asymmetric Induction of the Iodolactonization Reaction of\u03B1-Sulfurated \u03B3-Unsaturated Amides" . . . . . . .
