The present disclosure also provides pharmaceutical compositions and kits comprising the compounds, or pharmaceutically acceptable salts thereof, and methods of treating or preventing diseases or disorders (e.g., diseases or disorders associated with BCL-2, MYC, CCND1, MCL-1, ALK, KRAS-G12D) by administering to a subject in need thereof the compounds, or pharmaceutically acceptable salts thereof, or pharmaceutical compositions thereof.
专利号:US-9703192-B2 优先权日:2012-09-15 标 题:Onium compounds and methods of synthesis thereof 发明人:LABEAUME PAUL J 权利人:ROHM & HAAS ELECT MAT 摘要:New onium salt compounds and methods for synthesis of such compounds are provided. Preferred methods of the invention include (a) providing an onium salt compound comprising a sulfonate component having an electron withdrawing group; and (b) treating the onium salt compound with a halide salt to form a distinct salt of the onium compound. The present onium compounds are useful as an acid generator component of a photoresist composition.
专利号:US-10479754-B2 优先权日:2015-09-16 标题 :Synthesis of methacrylic acid from methacrolein-based alkyl methacrylate 发明人:KRILL STEFFEN; GROEMPING MATTHIAS; LYGIN ALEXANDER 权利人:ROEHM GMBH 摘要:The present invention relates to a process for preparing alkyl methacrylates, especially MMA, and methacrylic acid, based on methacrolein, which has been oxidatively esterified in a second process stage. Methacrolein is obtainable in principle from C2 and C4 units. The present process has the advantage that the alkyl methacrylate and methacrylic acid can be obtained in a simple manner, in high yields and high purities, either as a mixture or as isolated product streams. In particular, the process of the invention has the great advantage that especially the ratio of the desired methacrylic acid and alkyl methacrylate, especially MMA, products can be adjusted freely within a wide range and varied by chemical engineering measures and operating parameters.

参考标题:Evolution Of The Total Syntheses Of Ustiloxin Natural Products And Their Analogues 作者:Pixu Li,Cory D. Evans,Yongzhong Wu,Bin Cao,Ernest Hamel,Madeleine M. Joullié |发布日期:2008.2.1 摘要:Synthetically Challenging Chiral Tertiary Alkyl-Aryl Ether Linkage. The First Total Synthesis Of Ustiloxin D Was Achieved In 31 Linear Steps Using An S(N)Ar Reaction. An Noe Study Of This Synthetic Product Showed That Ustiloxin D Existed As A Single Atropisomer. Subsequently, Highly Concise And Convergent Syntheses Of Ustiloxins D And F Were Developed By Utilizing A Newly Discovered Ethynyl Aziridine Ring-Opening
