Synthesis of some triazolothienopyrimidin-5(4H)-ones

A series of hitherto unreported 1-(un)substituted-4-phenyltriazolothienopyrimidin-5(4H)-ones (8a-k) have been synthesized by the condensation of 2-hydrazino-3-phenylthienopyrimidin-4(3H)-ones (7a,b) with various one-carbon dono

METHYL N-ARYLDITHIOCARBAMATES: USEFUL REAGENTS FOR THE ANNELATION OF PYRIMIDINES AND 1,3-OXAZINES TO FIVE-MEMBERED HETEROCYCLIC RINGS

The reaction of methyl N-aryldithiocarbamates with ?-excessive heteroaromatic o-amino acid derivatives leads to the annelation of 4-oxo-2-thioxopyrimidines, 2,4-dioxopyrimidines or 2-arylamino-1,3-oxazines, depending on the reaction conditions.

Studies on Fused-ring Mesoionic Thiazolothienopyrimidine Systems

Cyclodehydration of 2-carboxymethylmercaptothienopyrimidin-4(3H)-ones (IV) have been studied.IV (R3=R4=Ph and R3=Me,R4=Ph) on reaction with acetic anhydride and pyridine mixture readily yield stable fusedring mesoionic systems (VI).While IV (R3=Ph,
