P(CH(3)NCH(2)CH(2))(3)N as a dehydrobromination reagent: synthesis of vitamin A derivatives revisited.

Andrzej E Wróblewski et al.

The Journal of organic chemistry, 67(2), 420-425 (2002-01-19)

Although P(CH(3)NCH(2)CH(2))(3)N (1) was found to be less effective than 1,5-diazabicyclo[4.3.0]non-5-ene (DBN) or 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in the removal of hydrogen bromide from vitamin A intermediates 13-cis-10-bromo-9,10-dihydroretinyl acetates (6) and 14-bromo-9,14-dihydroretinyl acetate (11) when the reaction was carried out in refluxing

Preparation of diazabicyclo[4.3.0]nonene-based peptidomimetics.

Craig A Hutton et al.

The Journal of organic chemistry, 72(18), 6865-6872 (2007-08-10)

Several functionalized diazabicyclo[4.3.0]nonenes and other heterocycles have been prepared as potential peptidomimetic scaffolds. A novel and efficient method has been developed for the preparation of N-substituted gamma-lactams 13. Preparation of amidine-containing 1,5-diazabicyclo[4.3.0]nonenes 43 and 44 has been achieved through Hg-mediated

Nucleophilicities and carbon basicities of DBU and DBN.

Electrospray ionization mass spectrometric analysis of chemical reactions of dissolution of selenium in strongly basic amines.

Ryuichi Arakawa et al.

Journal of mass spectrometry : JMS, 40(1), 66-69 (2004-12-08)

When elemental selenium was added to a strongly basic amine, 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) or 1,5-diazabicyclo[4.3.0]non-5-ene (DBN), the selenium started to dissolve and the solution turned dark brown. We investigated the chemical reaction of this selenium dissolution process by electrospray ionization mass

Recent progress in oligonucleotide synthesis.

W Pfleiderer et al.

Nucleic acids symposium series, (7)(7), 61-71 (1980-01-01)

It was found that some improvements in oligoribo- and oligo-2'-deoxyribonucleotide synthesis via the phosphotriester approach could be achieved using the p-nitrophenylethyl group for phosphate protection due to its stability in the condensation step and its clean removal of DBU and

Superbase route to supertetrahedral chalcogenide clusters.

Characterization of enhanced-fluidity liquid hydrophilic interaction chromatography for the separation of nucleosides and nucleotides.

Gwenaëlle S Philibert et al.

Journal of chromatography. A, 1218(45), 8222-8230 (2011-10-07)

Hydrophilic interaction chromatography (HILIC) is a liquid chromatographic separation mechanism commonly used for polar biological molecules. The use of enhanced-fluidity liquid chromatography (EFLC) with mixtures of methanol/water/carbon dioxide is compared to acetonitrile/water mobile phases for the separation of nucleosides and

Friedel-Crafts acylation of pyrroles and indoles using 1,5-diazabicyclo[4.3.0]non-5-ene (DBN) as a nucleophilic catalyst.

James E Taylor et al.

Organic letters, 12(24), 5740-5743 (2010-11-17)

1,5-Diazabicyclo[4.3.0]non-5-ene (DBN) has been shown to be an effective catalyst for the regioselective Friedel-Crafts C-acylation of pyrroles and indoles in high yields. A detailed mechanistic study implies that DBN is acting as a nucleophilic organocatalyst, with the X-ray crystal structure
