The nucleophilic ring opening of gem dicyano epoxides by N-substituted or N-N′ disubstituted thioureas leads to 2-imino 4-thiazolidinones, via postulated cyanoformyl intermediates, compounds 7 can exist in tautomeric equilibrium with a tautomeric 2-amino 4-hydroxy thiazolines. However, the cyanoformyl intermediates evolve differently when dicyano epoxides are reacted with 2-thioxobenzoxazole, 2-(aryl cyanoformyl) methylene be.
