A green and sustainable electrochem. oxidative dearomatization of 2-arylthiophenes was reported. The variation of substitution patterns afforded easy access to both C2/C3 and C2/C5 difunctionalized dearomative dihydrothiophenes such as I [R = Ph, 3-FC6H4, 2-pyridyl, etc.; R1 = OAc, OC(O)Et]. The synthetic utility of the resulting dihydrothiophenes was further demonstrated by the concise synthesis of a pyridazinone analog with interesting vasodilator activity.
