efficient alkylation of β-chloro ketones and their derivatives was achieved by means of domino dehydrochlorination/Mn-enabled radical-based alkyl-alkyl cross-coupling reaction. In situ-generated α,β-unsaturated ketones and their analogues were identified as the reaction intermediates. Known bioactive compounds, such as melperone and azaperone, could be easily prepared from β-chloropropiophenone in two
β-氯酮及其衍生物的高效烷基化是通过多米诺脱氢/基于锰的自由基基烷基-烷基交叉偶联反应实现的。原位生成的α,β-不饱和酮及其类似物被确定为反应中间体。已知的生物活性化合物,例如美蓬酮和氮杂哌酮,可以很容易地由β-氯丙苯酮分两步制备。
