A convenient synthesis of 5α,8α, 14α, 17α-5,6,8,9,14,15,17,18—octahydro-5,17:8,14-diepoxydibenzo[e,e']benzo[1,2-a:4,5-a'dicyclooctene (2) is described. This molecular cleft represents the parent of a new class of chiral molecular tweezers. It forms a clathrate with ethyl acetate which is stable even after 12 hours at 0.1 Tort. The structure of 2 was established by spectral and X-ray data.
方便合成5α,8α,14α,17α-5,6,8,9,14,15,17,18-八氢-5,17:8,14-二环氧二苯并[e,e']苯并[1,2描述了-a:4,5-a′二环辛烯(2)。这种分子裂隙代表了一类新的手性分子镊子的母体。它与乙酸乙酯形成包合物,即使在0.1 Tort下经过12小时也能保持稳定。2的结构由光谱和X射线数据确定。
