2-BTSO2CF2H was used as an efficient electrophilic –SCF2H synthon for the first time for the metal-free electrophilic difluoromethylthiolation of indoles.
Substituted indoles have been condensed with N-benzyl-4-piperidone to give 3-(1-benzyl-1,2,3,6-tetrahydropyridin-4-yl)-1H-indoles. Under basic conditions, 5-, 6-, and 7- (but not 4-) substituted indoles give reasonable yields of the product. For condensation with 4-substituted indoles, acidic conditions and the presence of at least a 3-fold excess of N-benzyl-4-piperidone are beneficial. Under basic

Palladium-catalysed aminocarbonylation of 7-iodoindole derivatives (the parent compound and 5-bromo-7-iodoindole), as well as 5-iodoindole with various primary and secondary amines, including amino acid esters and chiral diamines, was carried out. In this way, a highly selective doublecarbonylation reaction at the C-7 was performed resulting in the formation of the corresponding indol-7-ylglyoxylamides
1-(5-Carboxy- and 5-carbamoylindol-1-yl)propan-2-ones as inhibitors of human cytosolic phospholipase A2α: Bioisosteric replacement of the carboxylic acid and carboxamide moiety
Indole-5-carboxylic acids and -carboxamides with 3-aryloxy-2-oxopropyl residues in position 1 were previously reported to be potent inhibitors of cytosolic phospholipase A(2)alpha (cPLA(2)alpha) isolated from human platelets. In continuation of our attempts to develop novel cPLA(2)alpha inhibitors, a number of derivatives of these substances characterized by bioisosteric replacement of the carboxylic acid and carboxamide
