(S,S)-bis p-Tolylsulfinylmethane was shown to react with aromatic aldehydes with a high diastereoselectivity. In contrast, ,β-unsaturated aldehydes, giving only the elimination products, are in one step transformed into 4-substituted (E, E)-(S,S)-1, 1-bis (p-tolylsulfinyl)-1,3-butadiene.
(S,S)-双对甲苯磺酰基甲烷显示出以高非对映选择性与芳族醛反应。相反,仅给出消除产物的β-不饱和醛在第一步中转化为4-取代的(E,E)-(S,S)-1,1-双(对甲苯磺酰基)-1,3 -丁二烯。
