使用Na 2 SO 3作为生态友好型催化剂,可轻松合成5-芳基罗丹宁衍生物。获得2-巯基-3-芳基丙烯酸和苯并x硼烷衍生物
摘要:
利用罗丹宁,多种不同取代的醛和Na 2 SO 3作为乙醇中的良性催化剂,开发了一种通过Knoevenagel型反应合成5-芳基罗丹宁衍生物的简单,高效且环境友好的方法。将选择的5-亚芳基罗丹宁碱进行碱性水解,得到2-巯基-3-取代的丙烯酸。在这样的转化中,硼酸基团的存在被很好地耐受。在2-甲酰基苯基硼酸的情况下,该序列打开了获得新的苯并氧杂硼烷衍生物的途径。

The dual-specificity tyrosine-regulated kinase 1A (Dyrk1A) has gathered much interest as a pharmacological target in Alzheimer's disease (AD), but it plays a role in malignant brain tumors as well. As both diseases are multi-factorial, further proteinkinases, such as Clk1 and CK2, were proposed to contribute to the pathogenesis. We designed a new class of α-benzylidene–γ-butyrolactone inhibitors that
Invented is a method of inhibiting the activity/function of PI3 kinases using substituted thiazolones. Also invented is a method of treating one or more disease states selected from: autoimmune disorders, inflammatory diseases, cardiovascular diseases, neurodegenerative diseases, allergy, asthma, pancreatitis, multiorgan failure, kidney diseases, platelet aggregation, cancer, sperm motility, transplantation rejection, graft rejection and lung injuries by the administration of substituted thiazolones.
