A new series of antimicrobial oxazolidinones bearing unsaturated heterocyclic C-rings is described. Dihydrothiopyran derivatives were prepared from the saturated tetrahydrothiopyran sulfoxides via a Pummerer-rearrangement/elimination sequence. Two new synthetic approaches to the dihydrothiazine ring system were explored, the first involving a novel trifluoroacetylative-detrifluoroacetylative Pummerer-type
描述了带有不饱和杂环C-环的一系列新的抗微生物恶唑烷酮。通过Pummerer重排/消除序列由饱和的四氢噻喃亚砜制备二氢噻喃衍生物。探索了二氢噻嗪环系统的两种新的合成方法,第一种涉及新颖的三氟乙酰化-三氟乙酰化Pummerer型反应序列,第二种涉及四氢噻喃S,S-二氧化物中间体的直接脱氢。最终的类似物(例如4和13)代表了最近的临床前和临床恶唑烷酮的氧化同类物。
