Accessing N-Unprotected Unnatural α-Amino Acid Esters by Half-Sandwich Chiral-at-Ruthenium Aldehyde Catalysis: Scope and Mechanistic Study
{{output}}
Chiral aldehyde catalysis has emerged as an efficient and step-economical protocol for constructing unnatural α-amino acids and related esters. Herein, we report the application of a half-sandwich chiral-at-ruthenium complex featuring an aldehyde group as a v... ...
