An electrochemical method for synthesizing 1,2,4,5-tetrasubstitutedimidazoles was developed under undivided electrolytic conditions. This synthesis was specifically realized based on electrochemical C(sp3)–H amination via enamines and amines. Readily available starting materials were used, avoiding the use of both transition metals and oxidants. The practicability of the method lies in its broad substrate
The present invention relates to a compound represented by formula (I):
a salt of the compound, or a solvate of the compound or the salt; a drug containing any of the compounds, the salts, and the solvates; a preventive and/or therapeutic agent for an ischemic disease containing any of the compounds, the salts, and the solvates; and a platelet coagulation inhibitor containing any of the compounds, the salts, and the solvates. The compound of the present invention is useful as a strong platelet coagulation inhibitor without inhibiting COX-1 or COX-2.
