Synthesis of ethyl 5-acetyl-1-R-4-aryl-6-hydroxy-6-methyl-2-oxopiperidine-3-carboxylates
摘要:
The reaction of arylidene acetylacetones and ethoxycarbonylacetamides in the presence of triethyl-amine was found to lead to the formation of ethyl 5-acetyl-1-R-4-aryl-6-hydroxy-6-methyl-2-oxo-piperidine-3-carboxylates.
