  在Swern条件下高效地一锅将吲哚转化为功能化的羟吲哚和螺氧杂吲哚体系

  摘要：

  在Swern条件下，带有3-或4-羟烷基链的吲哚衍生物与二甲基亚砜和草酰氯的反应导致了一个单锅，三组分过程，涉及三种不同的合成转化，即吲哚氧化为羟吲哚，引入氯羟吲哚C-3位的取代基和侧链中的羟基被氯取代，具有良好的总收率。将相同的条件应用于2-甲基吲哚，得到在其侧链上氧化的2-甲酰基吲哚衍生物。从一个带有2-羟烷基链的吲哚开始的反应提供了3-（2-羟烷基）氧吲哚。最后，将Swern条件应用于吲哚-3-丙酸或丁酸的衍生物，得到3-螺氧并吲哚内酯。

  An improved synthesis of dioxindole-3-propionic acid and some transformations of the C-3 hydroxyl group

  摘要：

  Dioxindole-3-propionic acid lactone (3) is obtained in 80% yield by oxidative cyclization of indole-3-propionic acid with t-BuBr/DMSO. In the presence of 18-crown-6 in DMSO, KCN opens the spirolactone ring of 3 at C-3 with the formation of 3-cyanooxindole-3-propionic acid (4a) in 14% yield. Methanolysis of the lactone is strongly promoted by DMAP, and the resulting 3-hydroxy ester (5) is converted into the 3-fluoro ester (6) with methyl DAST. Every attempt to isolate 3-fluorooxindole-3-propionic acid resulted in rapid intramolecular displacement of fluorine by the free carboxyl group to reform the spirolactone. The 3-hydroxy ester is converted into the 3-chloro ester (9) with SOCl2/Et3N. The halogen is readily displaced by nucleophiles (e.g., N3-, CN-, NH3, AcO-, H2O) to generate the corresponding methyl 3-X-oxindole-3-propionate. Saponification of the ester function provides the corresponding 3-X-oxindole-3-propionic acid. Acetylation of the 3-hydroxy ester provides a separable mixture of the O-acetyl (16) and N-acetyl (17) derivatives. As in the case of 3, the O-acetyl derivative undergoes hydrogenolysis at C-3, while the 3-hydroxyl function is stable to removal by hydrogenolysis.

  and oxalyl chloride under Swern conditions led to a one-pot, three-component process involving three different synthetic transformations, namely oxidation of indole to oxindole, introduction of a chlorine substituent at the oxindole C-3 position and substitution of the hydroxyl group in the side chain by chlorine, in good to excellent overall yields. The same conditions, applied to a 2-methylindole, afforded
