Toward the Development of a Structurally Novel Class of Chiral Auxiliaries:  Diastereoselective Aldol Reactions of a (1R,2S)-Ephedrine-Based 3,4,5,6-Tetrahydro-2H-1,3,4-oxadiazin-2-one

, 2016
Asymmetric aldol addition reactions have been conducted with (1R,2S)-ephedrine-derived 3,4,5,6-tetrahydro-2H-1,3,4-oxadiazin-2-one (2). Diastereoselectivities range from 75:25 to 99:1 for the formation of the crude non-Evans syn adducts 8a−h.

Impurity profiling of an alternative pathway to ephedrine/pseudoephedrine and methamphetamine from the precursors benzaldehyde and nitroethane

, 2023
Methamphetamine is produced using various routes from two predominant precursors, ephedrine/pseudoephedrine or phenyl-2-propanone (P2P). The multitude of synthetic routes results in many possible impurities (by-products or intermediates).
