Tandem Nucleophilic Reaction Leading to Hydrofurans: Application to One-Pot Synthesis of Antitumor Naphthofuran Natural Product
摘要:
The reaction of enolates of 1,3-dicarbonyl compounds (1) with 3,4-dibromo-2-butanone (2) afforded hydrofuran derivatives (4) or (5) in the presence of DBU in THF and the reaction was applied to the one-pot synthesis of antitumor naphthofuran natural products (29).
