  One-step spiroannulation using 1,2-bis(methylene)cycloalkane-magnesium reagents

  摘要：

  A one-step method for the synthesis of a wide variety of spirocyclic systems has been developed based on the reactions of bis-electrophiles with a series of new 1,3-diene-magnesium reagents, the magnesium complexes of 1,2-bis(methylene)cycloalkanes. The direct metalation of 1,2-bis(methylene)cycloalkanes with highly reactive magnesium in THF at ambient temperature generates the corresponding diene-magnesium reagents in high yields. Reactions of the diene-magnesium reagents with 1,n-dibromoalkanes produce a large number of spirocarbocycles containing an exocyclic double bond. The ring sizes of the accessible spiro compounds can be any combinations of four- to seven-membered rings. In most cases, the initially alkylated intermediates can be trapped by protonation, giving the corresponding bromo olefins. Significantly, treatment of the diene-magnesium reagents with bromoalkyl nitriles leads to a one-step synthesis of keto-functionalized spirocycles. The initial adduct is believed to be a Grignard reagent containing a cyano group. When a bromo nitrile containing a cyclic moiety is used as the bis-electrophile, the approach provides a direct access to dispiroenones.

  The pseudohelical hydrocarbons (R)-6, (S)-7, and (R)-8 and the helical hydrocarbon (P)-9, formally derived from the helical hydrocarbon (P)-4 by stepwise replacement of each of the four-membered rings by a five-membered ring, have been prepared. Their optical rotations vary systematically, both in magnitude and sign. Of the extremes, (P)-4 represents the usual case of a right-handed dextrorotatory

  伪螺旋烃（R）-6，（S）-7和（R）-8和螺旋烃（P）-9是通过逐步置换四种烃的形式正式衍生自螺旋烃（P）-4的五元环的五元环已经准备好了。它们的旋光度在大小和符号上都有系统的变化。在极端情况下，（P）-4代表右旋右旋螺旋的通常情况，而（P）-9代表代表右旋左旋螺旋的异常情况。为了使这些事实合理化，DFT计算了（P的旋转功率）已完成三元，四元和五元环的螺旋。结果表明，三元环的刚性螺旋与实验数据非常吻合，并且始终显示四元和五元环的柔性螺旋的正确符号和量级，Boltzmann平均旋光度为最多必须使用六个conformer。在后者的共形体中，内球键的一组大二面角对应于高的比旋度，而一组小二面角对应于低的比旋度。结果，玻尔兹曼平均值明显取决于所涉及的构象异构体的几何形状和重量。
