synthesis of (+)-cis,anti,cis-1,8,12,12-tetramethyl-4-oxatricyclo[6.4.0.02,6]dodecan-3-ol (+)-1g, an enantiomer of natural thapsane isolated from Thapsia villosa var minor, is accomplished starting from (R)-carvone, which revises the absolute stereochemistry of natural thapsanes.
首次对映体合成(+)-顺,反,顺-1,8,12,12-四甲基-4-氧杂三环[6.4.0.0 2,6 ] dodecan-3-ol(+)- 1g(一种对映体)从(R)-香芹酮开始可分离自Thapsia villosa var minor的天然thapsane,从而改变了天然thapsanes的绝对立体化学。
