Reaction of N‐(Per‐O‐acetyl‐β‐D‐glucopyranosyl)‐Nʼ‐(4ʼ,6ʼ‐diarylpyrimidine‐2ʼ‐yl)thioureas with Ethyl Bromoacetate

open access: yesJournal of Chemistry, Volume 8, Issue 3, Page 1355-1361, 2011., 2011
Some new 2‐iminothiazolidin‐4‐ones having pyrimidine ring have been synthesized by reaction of substituted N‐(per‐O‐acetyl‐β-D‐glucopyranosyl)‐Nʼ‐(4ʼ,6ʼ‐diarylpyrimidine‐2ʼ‐yl)thioureas with ethyl bromoacetate. The structure of isomeric products has been confirmed by spectroscopic methods, such as IR, 1H and 13C NMR.
