Two new dihydroagarofuran sesquiterpenes with a novel substitution pattern: 1-(-methyl)-butanoyl-2, 15-diacetoxy-4-hydroxy-9-(-)furancarboxy--dihydroagarofuran (1) and 1, 2-di-(-methyl)-butanoyl-4-hydroxy-9-(-)furanca...Two new dihydroagarofuran sesquiterpenes with a novel substitution pattern: 1-(-methyl)-butanoyl-2, 15-diacetoxy-4-hydroxy-9-(-)furancarboxy--dihydroagarofuran (1) and 1, 2-di-(-methyl)-butanoyl-4-hydroxy-9-(-)furancarboxy-15-acetoxy--dihydroagaro- furan (2) were isolated from Euonymus nanoides. Their structures were elucidated by means of 1H and 13C NMR spectroscopic studies, including 2D NMR technique.展开更多
