An efficient method for the synthesis of versatile intermediates for biologically interesting 13-deoxy- and 9,13-dideoxyphorbol ester analogs is described. First, more efficient synthetic routes to the bicyclic ketones 7 and 8, which are well-known intermediates for the synthesis of 13-deoxyphorbols, than the previous one were established. Second, 7 and 8 were successfully converted to the intermediates
描述了一种用于合成生物学上令人感兴趣的13-脱氧和9,13-二脱氧佛波酸酯类似物的通用中间体的有效方法。首先,建立了比双环酮7和8更有效的合成路线,双环酮7和8是众所周知的13-脱氧佛波醇的合成中间体。第二,7和8被成功地转化为中间体19,25和27为使用彼得森反应中,oxymercuration和氧化腈环加成作为关键步骤-9,13- dideoxyphorbols合成。
