Lithium aluminum amides [LiAl(NHR)4], 6a-6d, easily prepared in Et2O or THF from 1 equiv of LiAlH4 and 5 equiv of amine, proved to be efficient reagents for the synthesis of secondary amides from esters (approximately 100% with unhindered amines and 92% with tBuNH2). They also open aryl epoxides with very high regioselectivity to give 97-98% of the beta-amino-alpha-arylethanols (corresponding to the SN2 mechanism).
