functionalities into methylene groups; however, it generally requires harsh reaction conditions and a strategy with wider applications demands further development. Herein, a ruthenium-catalyzed Wolff–Kishner type reduction of ketones is developed with 31 examples under mild conditions. This strategy tolerates aryl and alkyl ketones with reactive functional groups including halogens, hydroxyls, carboxylic acid
经典的 Wolff-Kishner 还原在将羰基官能团转化为亚甲基的有机合成中起着关键作用;然而,它通常需要苛刻的反应条件,并且具有更广泛应用的策略需要进一步发展。在此,在温和条件下,用 31 个实例开发了钌催化的 Wolff-Kishner 型酮还原。该策略允许芳基酮和烷基酮具有反应性官能团,包括卤素、羟基、羧酸、不饱和官能团等。在使用水或甲醇作为溶剂时,以 32% 至 95% 的收率获得了相应的亚甲基产物。
