Highly Chemoselective Addition of Amines to Epoxides in Water
摘要:
[GRAPHICS]Aminolysis of a variety of epoxides by aliphatic and aromatic amines in water, in the absence of any catalyst with high yields, is reported. beta-Amino alcohols were formed under mild conditions with high selectivity and in excellent yields.
