products vibrindole A (3n), arsindoline A (3i), arundine (3o) and tris(1H-indol-3-yl)methane (3j). Additionally, the synthesis of streptindole was carried out via intermediate 3g. This methodology is well suited for the synthesis of bis(indolyl)methanes: it offers good yields of products, low sensitivity to moisture and oxygen, high tolerance to different functional groups on the aldehydes such as alkynes

The Legend of Spiro: An iridium-catalyzed desymmetrization reaction involving allylicdearomatization of indoles was developed. The six-membered-ring spiroindolenines were obtained in up to 99 % yield with 99 % ee and >95:5 d.r. When treated with a catalytic amount of tosylic acid, six-membered spiroindolenine undergoes six-to-seven-membered ring expansion, yielding hexahydroazepino[4,5-b]indole.
Spiro的传说:铱催化的脱对称反应涉及吲哚的烯丙基脱芳香化反应。以高达99%的收率和99%ee和> 95:5 dr的产率获得六元环螺环吲哚胺当用催化量的甲苯磺酸处理时,六元环螺吲哚环烯经历了六至七元环的扩环,产生六氢氮杂环庚烷[4,5- b ]吲哚。
THE FORMATION OF 1- AND 3-SUBSTITUTED INDOLES IN THE REACTION BETWEEN INDOLE AND SODIUM GLYOXYLATE
The reactionbetween indole and sodium glyoxylate under basic conditions produces, in addition to the expected sodium 3-indolylglycolate (3a), the 1-substituted derivative (4a). 3a partially condenses with unreacted indole and with 4a yielding the corresponding 3 ,3′-diindolyllmethane derivatives, 5a and 6a. All compounds were isolated and identified as methyl esters.

Kinetictarget-guidedsynthesis (KTGS) is a powerful screening approach that enables identification of small molecule modulators for biomolecules. While many KTGS variants have emerged, a majority of the examples suffer from limited throughput and a poor signal/noise ratio, hampering reliable hit detection. Herein, we present our optimized multifragment KTGS screening strategy that tackles these limitations
