Hine, Jack,Linden, Shwn-Meei,Kanagasabapathy, V. M.
, p. 5096 - 5099 (1985)
The reaction of phenyl glycidyl ether with diethylamine in butanone gives 3-(diethylamino)-1-phenoxy-2-propanol.Catalysis by phenol and five of its meta- and para-substituted derivatives gives catalysis constants that obey the Broensted equation well, wit

Azizi, Najmodin,Saidi, Mohammad R.
, p. 3649 - 3651 (2007/10/03)
(Chemical Equation Presented) Aminolysis of a variety of epoxides by aliphatic and aromatic amines in water, in the absence of any catalyst with high yields, is reported. β-Amino alcohols were formed under mild conditions with high selectivity and in excellent yields.
A new and efficient epoxide ring opening via poor nucleophiles: Indole, p-nitroaniline, borane and O-trimethylsilylhydroxylamine in lithium perchlorate
Heydari, Akbar,Mehrdad, Morteza,Maleki, Aziz,Ahmadi, Nafiseh
, p. 1563 - 1565 (2007/10/03)
Highly regioselective ring opening of 2,3-dimethyloxirane, 2-epoxyphenylether and allyl(2-epoxymethyl) ether are observed through reactions with poor nucleophiles such as indole, borane, O-trimethylsilylhydroxylamine, p-nitroaniline and sterically hindered tert-butylamine in the presence of 5.0 M lithium perchlorate-Et2O solution. These reactions are fast, convenient, with rather high yields and are carried out at ambient temperatures.

, p. 2435 - 2439 (2007/10/03)
Aminolysis of epoxides catalysed by calcium trifluoromethanesulfonate under mild reaction conditions is described. The novel method is very efficient in the synthesis of wide variety of β-amino alcohols with high regio- and stereoselectivity.
Enantioselective parallel synthesis using polymer-supported chiral Co(salen) complexes
Peukert, Stefan,Jacobsen, Eric N.
, p. 1245 - 1248 (2008/02/09)
(matrix presented) The kinetic resolution of epoxides with phenols catalyzed by a polymer-supported Co(salen) complex is applied to the first enantioselective catalytic synthesis of parallel libraries. The corresponding 1-aryloxy-2-alcohols are obtained i
