Blue-luminescent 5-(3-indolyl)oxazoles via microwave-assisted three-component coupling-cycloisomerization-Fischer indole synthesis.
نویسندگان
چکیده
Aryl-substituted 5-(3-indolyl)oxazoles are readily synthesized in a novel one-pot three-component synthesis consisting of a microwave assisted sequence of Sonogashira coupling, an acid-catalyzed cycloisomerization, and a concluding Fischer indole synthesis. All title compounds are intensely blue-luminescent with large Stokes shifts upon UV-irradiation. The experimental absorption spectra are rationalized by ZINDO-CI computations based upon DFT geometry optimization.

A generally applicable and high-yielding protocol for the synthesis of 3-substituted indole derivatives is described. Key features include microwave-assisted intramolecular areneealkene coupling of o-iodoanilino enamines, and expedient synthesis of o-iodoanilino enamine substrates employing N,O-acetal TMS ethers, which could be conveniently derived from the corresponding amides. Our unique proc...
