A simple iodine–DMSO-promoted multicomponent reaction for the synthesis of 2,4-disubstituted dihydrotriazole-3-ones
摘要:
A series of 2,4-disubstituted 1,2,4-triazole-3-ones 4 were synthesized via an iodine–DMSO-promoted multicomponent reaction of formaldehyde 1, amines 2 and hydrazines 3 in moderate yields.
