Methyl 2-acetamidoacrylate reacted with various 2-substituted indoles in the presence of catalytic amounts of AgSbF6 or AuPPh3NTf2 to provide the corresponding methyl 2-(2-substituted-1H4ndo1-3-yl)acrylates.
Organocatalyzed coupling of indoles with dehydroalanine esters: synthesis of bis(indolyl)propanoates and indolacrylates
Functionalized and substituted bis(indolyl)alkanes were synthesized from indoles and dehydroalanine esters in the presence of catalytic amounts of Brønsted acid. When 2- or 4-bulky substituted indoles were used, unusual elimination occurred to yield interesting indolyl acrylates.
