A novel approach to regioselectively substituted and stereoselectively α-Trifluoromethylated tryptamines is reported based on the ene reaction of Boc-protected 3-methyleneindolines with optically pure (R)-or (S)-Tert-butanesulfinyltrifluoroacetaldimine. B
Palladium-catalyzed annulation of haloanilines and halobenzamides using norbornadiene as an acetylene synthon: A route to functionalized indolines, isoquinolinones, and indoles

A general procedure for the palladium-catalyzed annulation of substituted haloanilines with norbornadiene gives functionalized indolines in 51-98% yield. These indolines can be rapidly converted to benzenoid- substituted indoles and tricyclic indolines. Extension to the use of substituted halobenzamides gives functionalized isoquinolinones in up to 86% yield.
An improved synthesis of N-Boc protected aryl amines

There are several known methods of protecting amines as their Boc derivatives. For less nucleophilic amines such as aryl amines these methods often give poor yields and are generally not satisfactory. Here, Boc aryl amines are obtained by first introducing two Boc groups followed by selective removal of one of them. This procedure works well for a number highly sterically hindered substrates as well as electron deficient and electron rich aryl amines.
