The present invention relates to bis(sulfonamide) compounds and pharmaceutically acceptable salts thereof. The present invention also relates to pharmaceutical compositions comprising these compounds and to their use as a medicament for the treatment and/or prevention of a disease, disorder or condition in which modulation of microsomal prostaglandin E synthase-1 activity is beneficial, such as pain, inflammation and cancer.
Catalytic Asymmetric Synthesis of Aromatic Spiroketals by SpinPhox/Iridium(I)-Catalyzed Hydrogenation and Spiroketalization of α,α′-Bis(2-hydroxyarylidene) Ketones
From spiro to spiro: An iridium(I) complex with a spiral P,N ligand (SpinPhox) is highly efficient in the catalytic asymmetric hydrogenation of α,α′‐bis(2‐hydroxyarylidene) ketones to afford the corresponding aromatic spiroketals in high yields with excellent diastereo‐ and enantioselectivities (see scheme). The complex plays a dualrole in the reaction, acting as catalyst for both the hydrogenation
and tetrahydrofurobenzofuran systemsvia an in situ ring-expansion of the cyclopropane carbaldehydes followed by a [2 + n] cycloaddition with the quinone derivatives. The transformation not only unveils a new reaction mode of cyclopropane carbaldehydes with quinone methides/esters, but also promotes a step-efficient diastereoselective route to the sophisticatedly fused oxygen tricycles that can be
在这里,我们报告了四氢呋喃苯并吡喃和四氢呋喃苯并呋喃体系的直接一锅合成方法,方法是通过环丙烷甲醛的原位扩环,然后与醌衍生物进行 [2 + n ] 环加成。该转化不仅揭示了环丙烷甲醛与醌甲基化物/酯的新反应模式,而且还促进了一种高效的非对映选择性路线,可以进一步脱氢得到有价值的二氢-2H-呋喃[2 ,3- b ]铬烯框架。
Olefin skeletal rearrangement enabling access to multiarylated <i>N</i>-sulfonyl amidines
A base-promoted olefin skeletalrearrangement strategy from para-quinone methides (p-QMs) and N-fluoroarenesulfonamides is reported, enabling direct nitrogen insertion of olefins to produce a series of multiarylated (Z)-N-sulfonyl amidines with complete stereoselectivity and generally good yields. Using p-QMs without o-hydroxy substituents gave triarylated N-sulfonyl amidines, whereas tetraarylated
报道了一种由对醌甲基化物( p -QMs)和N-氟芳烃磺酰胺进行碱促进的烯烃骨架重排策略,使得烯烃能够直接氮插入,生成一系列具有完全立体选择性的多芳基化( Z ) -N-磺酰脒,并且通常良好的产量。使用没有邻羟基取代基的对-QM得到三芳基化的N-磺酰脒,而四芳基化的N , N'-二磺酰脒是在邻羟基存在的情况下合成的。
