The Overman rearrangement of allylic sulfinyl trichloroacetimidates affords sulfinyl trichloroacetamides with high stereoselectivity and excellent yields. Bis-allylic substrates lead to amido 2-sulfinyl butadiene derivatives in excellent yields, with total chemo- and diastereoselectivity. The Diels-Alder cycloaddition of related dienes is controlled by the sulfoxide moiety.
烯丙基砜三氯乙酰亚氨酸酯的 Overman 重排以高立体选择性和优异的收率得到砜基三氯乙酰胺。双烯丙基底物以优异的收率得到酰胺 2-砜基丁二烯衍生物,具有完全的化学和非对映选择性。相关二烯的 Diels-Alder 环加成受亚砜基控制。
