(-)-Erinapyrone A 和 (-)-erinapyrone B 已成功通过少量步骤从双(2-(1,3-二硫烷基))甲烷、(S)-丙二醇和(R)-苯基环氧化物合成。然而,这些合成化合物的比旋光度比天然产物更高。通过使用对映体环氧化物,合成了erinapyrones A 和 B 的两种对映体,这些对映体显示出绝对值相同但符号相反的比旋光度。此外,还合成了外消旋化合物作为标准样品,用于在手性气相色谱柱上进行光学分辨率分析。
(-)-Erinapyrone A and (-)-erinapyrone B have been synthesized in short steps from bis-2-(1,3-dithianyl)methane, (S)-propylene oxide and (R)-benzyl glycidyl ether. These synthetic compounds, however, showed higher specific rotation values than those of the natural products. Both enantiomers of erinapyrones A and B were synthesized by the use of antipodal epoxides. These enantiomers showed same specific rotation values with reverse signs. The racemic compounds were also synthesized as standard samples for analysis on chiral gc column for optical resolution.

Erinapyrones A and B from the Cultured Mycelia of<i>Hericium erinaceum</i>
Novel γ-pyrones, erinapyrones A and B, were isolated from the culture-broth of Hericium erinaceum mycelia. These compounds had cytotoxicity toward HeLa cells.
