Synthesis of functionalized pyrroles and 6,7-dihydro-1H-indol-4(5H)-ones by reaction of 1,3-dicarbonyl compounds with 2-azido-1,1-diethoxyethane
摘要:
The condensation of 1,3-dicarbonyl compounds with 2-azido-1,1-diethoxyethane and subsequent cyclization allowed an efficient synthesis of a variety of pyrroles and 6,7-dihydro-1H-indol-4(5H)-ones. (c) 2006 Elsevier Ltd. All rights reserved.

pyrolysis of various N-(2′-hydroxyethyl)-3-amino propenoates 1–6 and N-(2′-hydroxy-2′-phenyl ethyl)-3-amino propenoate 7–9 at 390°–420°C leads respectively to formylpyrroles 11–16 and benzoylpyrroles 17–19 and, in some cases, to substituted oxazoles 36–39. The results are best explained by the intermediate formation of dicarbonyl derivative followed either by an intramolecular thermal crotonisation
