Studies on the synthesis and interconversion of isomeric triazolothienopyrimidines. Part III. Cyclization reactions of 2‐amino‐3‐(1H‐1,2,4‐triazol‐3‐yl)thiophenes
摘要:
Isolation of 2-amino-3-(1 H -1,2,4-triazol-3-yl)thiophenes in the hydrolytic cleavage reactions of isomeric triazolothienopyrimidines is reported. The 2-amino-3-triazolylthiophenes on reaction with one carbon donors were found to cyclize to 1,2,4-triazolo[1,5- c ]thienopyrimidines, exclusively.
