An effective synthetic protocol of structurally diverse 4-acyloxy-1,2-dihydroquinoline compounds has been accomplished by a gold(I)-catalyzed tandem [3,3]-rearrangement and intramolecular hydroamination of propargylicesters, affording the desired products in good yields....
Compounds of Formula 1, as shown below and defined herein:
pharmaceutically acceptable salts thereof, synthesis, intermediates, formulations, and methods of disease treatment therewith, including treatment of cancers, such as tumors driven at least in part by TAK1 or for which an appropriate TAK1 inhibitor is effective. This Abstract is not limiting of the invention.

to have potent protein kinase and topoisomerase I inhibitory activities. Disclosed herein is the photochemical synthesis of the indolocarbazole ring system from N-allenyl-2-iodoanilines. The tandem protocol included visible-light-mediated 5-exo-trig radical cyclization and subsequent radical dimerization, followed by acid-promoted deprotection and intramolecular Mannich cyclization. This strategy showed
吲哚并咔唑生物碱及其衍生物被发现具有有效的蛋白激酶和拓扑异构酶 I 抑制活性。本文公开了由N-烯基-2-碘苯胺光化学合成吲哚并咔唑环系统。串联方案包括可见光介导的 5- exo - trig 自由基环化和随后的自由基二聚化,然后是酸促进的去保护和分子内 Mannich 环化。该策略表现出优异的官能团耐受性,并成功应用于天然产物噻帕唑 B 和 D 的简明合成。
