    • Typical Experimental Procedure for Cyclization of Thioureas with Epoxides Thiourea 2 (5 mmol) was added to a stirred mixture of DMF (20 mL) and epoxide 1. The reaction was monitored by TLC until completion. The temperature of this reaction was kept at 70°C (or r.t, for 72 h, then the solvent was removed by distillation at reduced pressure. The residual was purified on silica gel (PE-EtOAc-CH2Cl2, 10:1:1) to give thiazolindinimes 3 as white crystals.
