Abstract: | The synthesis of new chiral phase‐transfer catalysts based on the optical camphor is described. The alkylation of the benzophenone imine of glycine tert‐butyl ester with benzyl bromide in the presence of new chiral phase‐transfer catalysts afforded the desired alkylation product in good yields and up to 39% ee. |
