A variety of 3,3-disubstituted 2-indolinones have been prepared by treatment of 3-bromo-3-alkyl-2-indolinones with dienophiles/nucleophiles in the presence of cesium carbonate. Application of this general strategy has facilitated the total syntheses of the reverse prenylated marine natural products (+/-)-flustramine A and (+/-)-flustramine C. [Structure: see text]
通过在碳酸铯存在下用亲二烯体/亲核试剂处理3-溴-3-烷基-2-吲哚酮制备了各种3,3-二取代的2-吲哚酮。该通用策略的应用促进了反向异戊酸酯化的海洋天然产物(+/-)-氟链胺A和(+/-)-氟链胺C的总合成。[结构:参见文本]
