The anodic diacetoxylation of A7-acety-lindoles (or A7-acetylindoline) in acetic acid and in the presence of a base affords the corresponding 2,3-diacetoxyindoline (Scheme 104) [191]. A 2,3-diacetoxylation of A7-carbomethoxypiperidine is also observed [192]. 

The oxidation of 2,3-dimethylindole with peroxodisulfate and peroxomonosulfate yields 3-methy-lindole-2-carbaldehyde (136) (88JCS(P2)1065). The reaction proceeds in three steps, namely electrophilic attack of the peroxide at C-3 to give an indolenine intermediate (134), then peroxide attack on the enamine tautomer (135), and hydrolysis (Scheme 26) (93JOC7469).

The condensed indole, liZ-benzol lindole 706, under the same conditions, was coupled with 3-bromo-l-phenylprop-2-yn-Tone to furnish a mixture of 3- 707 and 2- 708 ethynylindoles in 45% overall yield (Equation 170) <2006TL7139>.

A solution of 3-formylchromone 1 (2.5 mmol) in an excess of indole or IV-methy-lindole (7.5 mmol) was heated at 85-90 °C for 5h. Completion of the reaction was determined by the appearance of the solid reaction mixture. The precipitate, obtained from the hot solution, was twice recrystallized from n-butanol/p-xylene (4 1), washed with ethanol, and dried at 90 °C for 1 day to give compound 2 as colorless crystals.

Both 2- and 3-vinylindoles take part quite readily as 4 components in Diels-Alder cycloadditions often, but not always, these employ A-acyl- or A-arylsulfony-lindoles, in which the interaction between nitrogen lone pair and 7r-system has been reduced. The example below shows how this process can be utilised in the rapid construction of a complex pentacyclic indole. ... 

This field is heavily dominated by the chemistry of dimethyldioxirane (DMD, 107) which, because of its ready availability and unique reactivity, has become a useful oxidant in the organic chemist s repertoire of reagents. The utility of DMD lies in its mildness and consequent ability to provide labile products which are not available by other methods. For example, substituted benzofurans 108 [94SYN111] as well as N-acy lindoles 110 [94JOC2733] are converted to the labile epoxides 109 and 111, respectively, in excellent yields upon treatment with DMD.
