Diversity of the Tryptophanase Gene and Its Evolutionary Implications in Living Organisms
Tryptophanase encoded by the gene tnaA is a pyridoxal phosphate-dependent enzyme that catalyses the conversion of tryptophan to indole, which is commonly used as an intra- and interspecies signalling molecule, particularly by microbes.

3-(1<em>H</em>-Indol-3-yl)-4-(morpholin-4-yl)cyclobut-3-ene-1,2-dione
3-(1<em>H</em>-Indol-3-yl)-4-(morpholin-4-yl)cyclobut-3-ene-1,2-dione was obtained in good yields (72–82%) by nucleophilic substitution of 3-chloro-4-(1<em>H</em>-indol-3-yl)cyclobut-3-ene-1,2-dione with morpholine.

The natural product sesquiterpenyl indoles are structural hybrids from farnesyl pyrophosphate and tryptophan or its precursors, often with unusual and complex structural features, many of them with interesting biological activities. In this review the compounds of this class known until now are classified, a biosynthetic approach of each group is ...

Dialkylation of Indoles with Trichloroacetimidates to Access 3,3-Disubstituted Indolenines
2-Substituted indoles may be directly transformed to 3,3-dialkyl indolenines with trichloroacetimidate electrophiles and the Lewis acid TMSOTf. These reactions provide rapid access to complex indolenines which are present in a variety of complex natural ...
