General description

Ethoxycarbonyl isothiocyanate reacts with 2-amino-tetrahydrobenzo[b]thiophene derivatives to yield tetrahydrobenzo[b]thiophen-2-thiourea derivatives.

Application

Ethoxycarbonyl isothiocyanate has been used in the synthesis of:
  • pyrazolo[1,5-a][1,3,5]triazine derivatives, potential inhibitors of protein kinase CK2
  • fused thiophene derivatives, having antibacterial and antifungal activities
  • 4-thiouracil derivatives
  • thiocarbamides from stannylarenes
  • 1,3,5-triazin-2-one-4-thiones from 2-amino-2-oxazolines
  • N-acylthioureas from aminodeoxy sugars
