called the melatoninrhythmenzyme, is thought to play an important regulatory role in circadian rhythm in animals and people. A series of analogues were synthesized in which indole and coenzyme A were linked via ketone tethers as designed inhibitors of this enzyme. These compounds were tested against purified serotonin N-acetyltransferase. The parent ketone compound was found to be as potent as an amide

asymmetric hydroarylations of activated, electron-poor olefins with activated, electron-rich arenes have been described. In contrast, only a few approaches that can handle unactivated, electronically neutral olefins have been reported and invariably require transition metal catalysts. Here we show how an efficient and highly enantioselective catalytic asymmetric intramolecular hydroarylation of aliphatic

A one-pot, site isolated base (PS-BEMP) and acid (Si-TsOH) catalyzed cyclization cascade to azaspirocyclic molecules is reported; the reaction is simple to perform, atom efficient (water is the only byproduct) and broad in its scope to a diverse range of azaspirocyclic products.

A series of 2-(3'-indolyl)tetrahydrofurans have been prepared by a DDQ-mediated oxidative cycloetherification process. Performing the reaction under biphasic conditions prevents reductive cleavage of the products by the spent oxidant (DDQH(2)).

Synthesis of 1-substituted tetrahydrocarbazole is accomplished by TfOH catalyzed reaction of 3-substituted indoles tethered with secondary and tertiary alcohols. The reaction was generalized for a variety of substrates and was extended to the synthesis of 2,3,3a,6-tetrahydro-1H-pyrido[3,2,1-jk]carbazole and carbazoles.
1-取代的四氢咔唑的合成是通过TfOH催化的与仲和叔醇连接的3-取代的吲哚的反应来完成的。该反应被推广用于多种底物,并扩展到2,3,3a,6-四氢-1 H-吡啶并[3,2,1- jk ]咔唑和咔唑的合成。
