The reactions of aluminum carbenoids with alkyl- and phenyl-substituted allenes and cyclic allenes are studied. An efficient method for the synthesis of substituted spiropentanes was developed. 1,2-Cyclononadiene was selectively converted into bicyclo[7.1.0]dec-1-ene. An unusual transformation of α-methylphenylallene into a spiroindane derivative under the action of Et3Al–CH2I2 was found.
研究了铝类化合物与烷基和苯基取代的烯和环烯的反应。开发了一种有效的合成取代螺环戊烷的方法。将1,2-环己二烯选择性地转化为双环[7.1.0] dec-1-ene。发现在Et 3 Al–CH 2 I 2的作用下,α-甲基苯丙烯不寻常地转变为螺茚满衍生物。

Reaction of substituted allenes and diazomethane gives rise to optically active methylenecyclopropane and spiropentane derivatives in the presence of dissymmetric copper chelates, bis[N-(R and S)-α-phenethylsalicylaldiminato]copper(II).

large extent by the nature of the substituents in the pyrazoline ring. The structures of phthalimidoazimines were established based on the NMR spectra and X-ray diffraction data. Thermal conversions of the resulting adducts, which proceeded either with retention or with opening of the spiro-fused cyclopropane ring, were studied.
