were evaluated. Drastically reduced yield in both entries confirmed that Mg itself is insufficient to facilitate the reaction. The reaction was also benchmarked against photochemical conditions by using both RAE and the corresponding free carboxylic acid as a substrate (entry 13), confirming that the electrochemical method described here offer much simpler reaction conditions, an important aspect for large-scale execution (vide infra). Finally, under the optimized conditions, the corresponding aryl bromide poorly reacted, resulting in low yield of 13 due to preferential consumption of RAE 10 (entry 14). This reactivity difference was overcome by slow addition of RAE 10 via a syringe pump, furnishing the product in the identical yield that was obtained by using ArI (compare entry 10 and entry 12). After identifying the practical aminoalcohol "cassettes" 10 and 12 and the requisite optimal crosscoupling conditions, their practical and scalable synthesis was pursued. The analogous oxazolidine synthesis described by Schmidt and Li was modified to improve yields and operational simplicity by minimizing chromatography. The synthesis can be readily achieved as depicted in even less than a bulk chemical PPh3) after a sequence of trivial interconversions such as esterification, condensation with pivalaldehyde, N-protection followed by hydrolysis of the ester.
