A highly stereoselective aldol reaction of the aldehyde 11, derived from (+)-tricarbonyl(η6-2-trimethylsilylbenzaldehyde)chromium(0) complex (4), with 2-trimethysilyloxyfuran afforded the γ-lactone derivative 13. The γ-lactone 13 was subsequently converted into three antitumor styryllactones, (+)-goniofufurone, (+)-goniobutenolide A, and (−)-goniobutenolide B.
醛的高立体选择性醛醇缩合反应11,从(+)衍生的-三羰基(η 6 -2- trimethylsilylbenzaldehyde)铬(0)配合物(4),用2- trimethysilyloxyfuran得到γ内酯衍生物13。γ-内酯13随后被转化为三种抗肿瘤苯乙烯基内酯,(+)-goniofufurone,(+)-goniobutenolide A和(-)-goniobutenolideB。
