The tide compound was synthesised in the optically active form in seven steps from (4R,6R)-actinol in 34% overall yield. The relative configuration within the C15-key intermediate acetylenictriol, 2-E-5-((1S,4R;,6R)-1,4-dihydroxy-2,2,6-trimethylcyclohexyl)-3-methyl-2- penten-4-yn-1-ol, was determined by X-ray crystallographic analysis.
从(4 R,6 R)-肌动蛋白以七个步骤合成旋光形式的潮汐化合物,总产率为34%。C 15键中间体炔属三醇2- E -5-((1S,4 R ;,6 R)-1,4-dihydroxy-2,2,6-三甲基环己基)-3-甲基-通过X射线晶体学分析确定2-戊烯-4-yn-1-ol。
