Allyl sulfones can be conjugated to furnish vinyl sulfones via allyl silane intermediates. The stereoselectivity observed in the protodesilylation step provides a new method for stereoselective preparation of (E)-di-and trisubstituted vinyl sulfones.
烯丙基砜可以通过烯丙基硅烷中间体共轭以提供乙烯基砜。在原去甲硅烷基化步骤中观察到的立体选择性为立体选择性制备(E)-二和三取代的乙烯基砜提供了一种新方法。
