The present invention relates to 1,2,3-triazoles of formula:
useful for improving or restoring the intracellular calcium homeostasis and RyR-calstabin binding function in human and animal cells. The present invention also relates to methods for synthesizing said compounds, to pharmaceutical compositions containing them, and to the use thereof for preventing or treating skeletal muscle, heart and nervous system disorders.
3-allyl/3-allenyl-3-(thio)oxindole core remains a challenge in organic synthesis. Herein, we report a novel Rh2(esp)2 catalytic Doyle–Kirmse reaction to furnish the oxindole core, bearing unbiased NH as well as a quaternary stereogenic center at the 3-position, in good to excellent yields under mild conditions. These reactions are concise, practical, atom-economic, and highly efficient, and feature a TON

under mild aqueous basic conditions through [2,3]-sigmatropic rearrangement of propargyl/allyl sulfur-ylides derived from in situ-generated Rh-(E)-enalcarbene. Various synthetically challenging allene- and allyl-functionalized (E)-enals with a γ-C(sp3) quaternary center were obtained in good to high yields. InCl3-catalyzed cascadecyclization of allenyl-enal and aniline gave a valuable pyrrolo[1,2-a]quinoline
在此,我们报告了一种用于功能化烯醛的简单方法,该方法涉及水溶性N-甲氧基哒嗪鎓盐的烯醛转移反应。这种开瓶反应在温和的水性碱性条件下通过原位生成的 Rh-( E )-烯醛卡宾衍生的炔丙基/烯丙基硫叶立德的 [2,3]-σ 重排进行。以良好至高产率获得了具有 γ-C(sp 3 ) 季中心的各种合成具有挑战性的丙二烯和烯丙基官能化 ( E )-烯醛。InCl 3催化的烯丙基-烯醛和苯胺的级联环化产生了有价值的吡咯并[1,2- a ]喹啉基序。
