An efficient synthesis of β-amino alcohols from a variety of epoxides and primary
unbranched amines in the absence of any catalyst in high yields and regioselectivities
is reported. A variety of polar mixed solvent systems allow for the selective formation
of secondary amino alcohols over tertiary amino alcohols. The reaction scope extends
to a wide variety of aromatic and aliphatic substituted epoxides and primary amines
bearing complex functionality.
