Diversely substituted 1,2-oxathiine 2,2-dioxides, including 3,5,6-triaryl-, 3,6-diaryl-, 3,5-diaryl-, 5,6-diaryl- and selected fused heterocyclic analogues, have been efficiently obtained by the application of a mild Cope elimination of a 4-amino moiety from the requisite 4-amino-3,4-dihydro-1,2-oxathiine 2,2-dioxides, which themselves were readily obtained by the addition of sulfenes to enaminoketones
包括3,5,6-三芳基-,3,6-二芳基-,3,5-二芳基-,5,6-二芳基-和选定的稠合杂环类似物的不同取代的1,2-氧杂i啶2,2-二氧化物具有通过从必需的4-氨基-3,4-二氢-1,2-氧代草氨酸2,2-二氧化物中温和地消除4-氨基部分,可以有效地获得它们,它们本身很容易通过添加亚砜成烯氨基酮。
