Efficient synthesis of 2-aryl-6-methyl-2,3-dihydro-1H-pyridin-4-ones
摘要:
Syntheses of 2-aryl-6-methyl-2,3-dihydra-1H-pyridin-4-ones were achieved starting from corresponding beta-aryl-amino acids. This reaction sequence involved, as a key step, the condensation of an acid chloride with a diketone using SmI3 as catalyst. A final intramolecular cyclization furnished the attempted product.
