摘要
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 alpha-methylphenylallene into a spiroindane derivative under the action of Et(3)Al-CH(2)I(2) was found.
