Abstract
Abstract The reaction between a lithium enolate of an enantiomerically pure β‐hydroxyl carboxylate and an alkyl halide to give α‐alkyl‐β‐hydroxyl‐carboxylate with high diastereoselectivity (> 10:1 of anti ‐ preference) is generally known as the Fráter–Seebach alkylation. This reaction is found to be highly diastereoselective. The high diastereoselectivity is clearly evidenced in one experimental condition, in which only the anti ‐diasteromer forms.
