Understanding the origins of remote asymmetric induction in the boron aldol reactions of beta-alkoxy methyl ketones.

Understanding the origins of remote asymmetric induction in the boron aldol reactions of beta-alkoxy methyl ketones.

We report theoretical studies into the remote 1,5-stereoinduction shown by certain types of beta-alkoxy methyl ketones in boron-mediated aldol reactions with achiral aldehydes. For a range of common alkoxy groups, our calculations are in excellent agreement with experimentally observed diastereosele...
