Compounds of formula (I) or pharmaceutically acceptable derivatives thereof, and their use as pharmaceuticals, particularly as p38 kinase inhibitors.
An efficient, one-pot protocol for the synthesis of highly functionalized cyclopentenols has been accomplished starting from vinylethylene carbonates and bissulfonylmethanes. This protocol proceeds via sequential palladium-catalyzed decarboxylative allylation and oxidative cyclization in an operationally simple manner. A wide range of substrates is well-accommodated to afford diverse cyclopentenols
从乙烯基碳酸乙烯酯和双磺酰甲烷开始,已经完成了一种用于合成高度官能化的环戊烯醇的有效的一锅法。该协议通过顺序钯催化脱羧烯丙基化和氧化环化以操作简单的方式进行。广泛的底物可以很好地适应各种环戊烯醇,以中等至良好的产率和优异的选择性。进一步的对照实验表明,可分离的 ( Z )-烯丙醇(高达Z / E = >19:1)的选择性形成是后续级联氧化环化成功的基础。

copper-catalysed rearrangement of cyclic ethynylethylene carbonates has been discovered, and the in situ-formed allenal intermediates could react with a range of nucleophiles to furnish synthetically useful and highly functionalised products through the addition pathways. Mechanisticstudies reveal that the reaction proceeds through the base-mediated deprotonation as the key step to induce the rearrangement.
