Utinan, M. F. published the artcileSynthesis and properties of 2-amino-5-(3,5,6-trichloro-1,4-benzoquinon-2-yl)thiazoles, Related Products of catalysis-chemistry, the publication is Khimiya Geterotsiklicheskikh Soedinenii (1988), 692-8, database is CAplus.
Thiazoles (in the form of betaines) I (R2 = Me, R3 = H, Me, Ph, allyl, Ac; R2 = Et, R3 = Me) were prepared in 76-99% yields from benzoquinones II (R1 = Et) via an intermediate coumaran III by treatment with appropriate thioureas in EtOH or from I (R1 = Et) and thioureas in dioxane containing concentrated HCl.H2O. Treating I with FeCl3.6H2O in aqueous DMF gave 75-95% benzoquinones IV.
