Silicon as a directing group in the phosphine-catalyzed [2+3]-cycloaddition of aryl allenones with electron-deficient olefins.
This Communication describes a highly efficient phosphine-catalyzed [2+3]-cycloaddition reaction using alpha-trimethylsilyl-substituted aryl allenones and electron deficient olefins; both good yields and good asymmetric induction were obtained.
