3-thiazine derivatives is described. N-(2-(Cyclohex-1-en-1-yl)ethyl)benzamide and benzothioamide are used as the substrates, and the cationic fluorinating agent Selectfluor works as the fluoride source. The reaction yields a single diastereomer. The scope of this regioselective fluorination reaction is established by preparing thirty different spirooxazine and spirothiazine derivatives.
描述了用于合成氟取代的螺-1,3-恶嗪和螺-1,3-噻嗪衍生物的氟化诱导的分子内环化。以N- (2-(环己-1-en-1-基)乙基)苯甲酰胺和苯硫代酰胺为底物,阳离子氟化剂Selectflu为氟化物源。该反应产生单一非对映异构体。通过制备三十种不同的螺恶嗪和螺噻嗪衍生物,确立了该区域选择性氟化反应的范围。
