A modified orcinol reaction for RNA determination.

A MONG the various colorimetric methods for RNA estimation, the orcinol reaction of Mejbaum as modified by Schneider (1) remains the most sensitive and commonly employed technic for purine-bound ribose quantitation. Later attempts that were made to estimate pyrimidine nucleotides and nucleosides (2, 3) have also been based on the color reaction of ribose with orcinol and ferric chloride, which ...

Thiazole formation through a modified Gewald reaction

The synthesis of thiazoles and thiophenes starting from nitriles, via a modified Gewald reaction has been studied for a number of different substrates. 1,4-Dithiane-2,5-diol was used as the aldehyde precursor to give either 2-substituted thiazoles or 2-substituted aminothiophenes depending on the substitution of the α-carbon to the cyano group.
