A series of novel 6H‐1,3,5‐oxathiazine S,S‐dioxides were synthesized by the m‐CPBA oxidation (2.2 equiv) of 6H‐1,3,5‐oxathizines. The synthetic utilities of the newly synthesized cyclic sulfones were investigated. In a thermal condition, compounds 6H‐1,3,5‐oxathiazine S,S‐dioxides were found relatively stable, but Lewis acid‐induced thermal reaction afforded the corresponding amides. The plausible
一系列新颖6的ħ -1,3,5-恶噻嗪S,S -dioxides是由合成米6的-CPBA氧化(2.2当量)ħ -1,3,5- oxathizines。研究了新合成的环状砜的合成效用。在热条件下,发现化合物6 H -1,3,5-氧杂噻嗪S,S-二氧化物相对稳定,但路易斯酸诱导的热反应提供了相应的酰胺。此帐户中还讨论了从6 H -1,3,5-恶二嗪S,S-二氧化物获得酰胺的可能途径。
