以4-戊烯酸及(R)-4-苯基-2-噁唑烷酮为起始原料, 以氯化镁在三乙胺和三甲基氯化硅存在下催化的(R)-4-苯基-3-戊烯酰基-2-噁唑烷酮的埃文斯（Evans)反式羟醛缩合反应为关键步骤, 经9步反应合成了(－)-7(R)-羟罗汉脂素, 其光谱数据与文献报道的天然产物一致.

关键词: (－)-7(R)-羟罗汉脂素, 羟醛缩合, 催化, 全合成

The (－)-7(R)-hydroxymatairesinol has been synthesized utilizing 4-pentenoic acid and (R)-4- phenyl-2-oxazolidinone as starting materials via the asymmetric aldol reaction of chiral N-acyl-2-oxazolidinone catalyzed by magnesium chloride in the presence of Et3N and chlorotrimethylsilane as the key step in nine steps.

Key words: aldol reaction, catalyst, total synthesis, (－)-7(R)-hydroxymatairesinol
