中文摘要：

以甲基庚烯酮为原料经Wittig反应、水解、环氧化和分子内环化或开环等4步反应分别以6.4%和23.7%的总收率完成了天然产物3,7-二甲基-7-羟基-2-辛烯-1,6-内酯和（E）-6,7-二羟基-3,7-二甲基-2-辛烯酸的全合成,它们的结构经1H NMR,13C NMR和ESI-MS的确证.

英文摘要：

The total synthesis of 3,7-dimethyl-7-hydroxy-2-octen-1,6-olide and （E）-6,7-dihydroxy-3,7-dimethyl-2-octenic acid were carried out though Wittig reaction, hydrolyzation, epoxidation and intramolecular cyclization or ring-opening in overall yields of 6.4%and 23.7%using 6-methyl-5-hepten-2-one as raw materials, and their structures were characterized by 1H NMR, 13C NMR and ESI-MS spectral data.
