A highly efficient ruthenium-catalyzed stereospecific N-demethylative rearrangement of isoxazolidines to synthetically useful N–H-1,3-oxazinanes is described. 1,3-Oxazinanes are useful building blocks, which can be further converted to N–H-1,3-aminoalcohols in one step. This new method was used in a three-step gram-scale total synthesis of HPA-12 in an overall 24% yield.
