, p. 2022 - 2027 (2011)
The range and scope of the oxidative oxazoline-oxazinone rearrangement-hydrogenation sequence (OOOH)-a short, direct asymmetric synthesis of α-amino acids from carboxylic acids-was explored. The highest yet reported diastereoselectivity for hydrogenation of the oxazinone C=N bond (d.r.=>80:1) is disclosed and rationalized with the aid of ab initio molecular calculations.
