Odorous products of the chlorination of phenylalanine in water: Formation, evolution, and quantification
Freuze, Ingrid,Brosillon, Stephan,Herman, Dorine,Laplanche, Alain,Democrate, Christian,Cavard, Jacques
, p. 4134 - 4139 (2004)
To explain some of the possible origins of an odor episode which took place in a drinking water supply in the region of Paris (France), the chlorination reaction in water of phenylalanine was studied. This amino acid was chosen for first experiments becau
Metal-free, one-pot oxidative conversion of aldehydes to primary thioamides in aqueous media
Yadav, Arvind K.,Srivastava, Vishnu P.,Yadav, Lal Dhar S.

One-pot tandem reactions of a variety of aldehydes with aqueous ammonia, molecular iodine, and O,O-diethyl dithiophosphoric acid readily afford the corresponding primary thioamides. This is an inexpensive, practical, and metal-free way of accessing various thioamides from aldehydes in aqueous media. The pure products are obtained simply by filtration followed by successive washing with aqueous sodium thiosulfate and water. [Supplementary materials are available for this article.

Determining the scope of the lanthanide mediated, sequential hydroamination/C-C cyclization reaction: Formation of tricyclic and tetracyclic aromatic nitrogen heterocycles
Molander, Gary A.,Pack, Shawn K.
, p. 10581 - 10591 (2007/10/03)
The scope of the lanthanide mediated, sequential hydroamination/C-C cyclization reaction was determined for the formation of tricyclic and tetracyclic aromatic nitrogen heterocycles. An array of ring sizes was explored to determine the diastereoselectivity. The electronic characteristics of the aromatic ring was also varied to determine how it affected the cascade reaction. It was found that the benzo[a]quinolizine and the pyrido[2,1,a]isoindolizine ring systems formed with the highest diastereoselectivity (>20:1), regardless of the electronic characteristics of the aromatic ring. Additionally, a tetracyclic indole nitrogen heterocycle was formed with a 2.3:1 diastereomeric ratio. A novel procedure for substrate preparation is also presented.
