Synthesis of (1R,5R,6R)-2-(6-hydroxymethyl-5-isopropyl-2-methylcyclohex-2-enyl)-N- methoxy-N-methylacetamide 8 from R-(-)-phellandrene in six steps, and (3aR*,4S*,6R*,6aS*)- (6-hydroxymethyl-4-methoxy-2,2,6-trimethyltetrahydrofuro[3,4-d][1,3]dioxol- 4-yl)acetic acid methyl ester 17 from tetrabromoacetone and 2-methoxy-5-methylfuran in six steps, provided two key fragments which have been combined to
由R-(-)-水芹烯经六步合成(1R,5R,6R)-2-(6-羟甲基-5-异丙基-2-甲基环己-2-烯基)-N-甲氧基-N-甲基乙酰胺8,和(3aR *,4S *,6R *,6aS *)-(6-羟甲基-4-甲氧基-2,2,6-三甲基四氢呋喃[3,4-d] [1,3]二恶酚-4-基)乙酸由四溴丙酮和2-甲氧基-5-甲基呋喃分三步反应制得的丙烯酸甲酯17,提供了两个关键片段,这些关键片段已合并生成中间体,用于尝试构建eleutherobin的基本骨架。
