A novel method for the synthesis of 3,4-disubstitutedpyrrole-2,5-dicarboxylates from hydrazones derived from α-diazo esters
摘要:
Hydrazones obtained from alpha-diazo esters were converted to pyrroles when heated with thionyl chloride in alcohol. Among hydrazones, those substituted with a benzene ring on the beta-carbon to the ester are likely to give pyrroles in good yields. (C) 2013 Elsevier Ltd. All rights reserved.
