Abstract

There is a considerable literature precedent for the synthesis of β-amino alcohols, with the conversion of epoxides into the corresponding trans amino alcohols being a noteworthy example. 3, 4 and 5 Ring opening of epoxides is traditionally preferable to the ring opening of aziridines, 6 a function of their higher reactivity and ease of synthesis. An additional concern in our laboratory is waste minimization and the application of green chemistry principles. 7 The pharmaceutical ...
