  Oxyanion Orientation in Anionic Oxy-Cope Rearrangements

  摘要：

  Efficiency of chirality transfer in anionic oxy-Cope rearrangement depends solely on the orientational preference of the oxyanionic bond in the substrates with a single carbinol carbon chiral center. In chairlike transition-state conformations for the rearrangement of simplest substrates like anions generated from (E)-1-phenyl-1,5-hexadien-3-ol and (E)-1,5-heptadien-4-ol, the oxyanionic bond is more prone to adopt the pseudoaxial orientation. On the other hand, anions generated from (E)-2-methyl-1,5-heptadien-4-ol, (E)-5-tert-butyl-1-phenyl-1,5-hexadien-3-ol, and 4-(2'-methyl-1'-cyclohexenyl)-1-buten-3-ol undergo rearrangement via chairlike transition states in which the pseudoequatorial oxyanionic bond is favored. It can thus be surmized that there is a slight stereoelectronic preference for the pseudoaxial oxyanionic bond in the chairlike transition states for the rearrangement of substrates without steric constraints. Substitution at C5 of the basic 1,5-hexadien-3-ol framework of substrates, however, leads to 1,3-diaxial steric interaction in the chairlike transition states with pseudoaxial oxyanionic bond, and pseudoequatorial disposition of oxyanionic bond becomes more favorable.

  Methyl 6', 6'-didemethyl abscisate (5) was synthesized and assayed to elucidate the physiological activity of methyl substituents on the cyclohexene ring of abscisic acid (ABA). During this study two new chiral stereoisomeric analogs 6 and 7 were synthesized from l- and d-carvone. The rice seedling assay and germination assay of garden radish showed that 6'-methyl groups of ABA were not important in biological activity and that 5'-isopropenyl analogs 6 and 7 were inactive.

  为了阐明脱落酸（ABA）环己烯环上甲基取代基的生理活性，我们合成并检测了 6'，6'-二去甲基脱落酸甲酯（5）。在这项研究中，从 l-和 d-香芹酮合成了两种新的手性立体异构体类似物 6 和 7。水稻育苗试验和萝卜发芽试验表明，ABA 的 6'-甲基对生物活性并不重要，5'-异丙烯基类似物 6 和 7 没有活性。
