Combined directed metalation - cross coupling strategies. A regiospecific route to heteroring-annelated artho-naphthoquinones and a short synthesis of β-lapachone
摘要:
A general combined metalation - cross coupling methodology (Scheme 1) for the regiospecific construction of heteroring fused o-naphthoquinones 8 is described and its application to a short synthesis of the antimalarial/antitumor natural product beta-lapachone (14) is demonstrated.
