Indole and indolizines (heterocyclic aromatic compounds structurally and chemically isomeric with indoles) are an important class of N-fused heterocyclic compounds due to their interesting biological and optical properties. Different strategies for generating diverse collections of small molecules with indole and indolizine moieties have been : Ioana Otilia Ghinea, Rodica Mihaela Dinica.

escence upon its reaction with the formaldehyde. The method is specific for tryptophan – other indoles such as tryptamine and serotonin do not interfere. In a paper, Yamada (40) determined tryptophan and its metabolites in mouse brain using LC separation. Many papers have been published on the de-termination of amino acid residues in peptides. The principle of SFS technology is based on the measuring of the fluorescence intensity of a sample at different excitation and emission wavelengths. Since most chemical compounds have their .
G.G. Stokes was the first person who proposed to use fluorescence as an analytical tool in a lecture “On the application of the optical properties to detection and discrimination of organic substances” in Following are the important research works done in much earlier days (), which immensely contributed to the understanding. Fluorescence is an effect which was first described by George Gabriel Stokes in He observed that fluorite begins to glow after being illuminated with ultraviolet light. Fluorescence is a form of photoluminescence which describes the emission of photons by a .

A Brönsted acid-catalyzed one-pot synthesis of indoles from o-aminobenzyl alcohols and furans via in situ formation of aminobenzylfuran followed by its recyclization into the indole core proved to be efficient for a wide range of substrates. The resulting indoles can easily be transformed into other scaffolds, including 2,3- and 1,2-fused.
