An efficient chemoenzymatic route to the antidepressants (R)-fluoxetine and (R)-tomoxetine
Bracher, Franz,Litz, Thomas
, p. 877 - 880 (1996)
(S)-1-Phenyl-3-buten-1-ol (1), prepared in high optical purity by enzymatic resolution of the racemate, is a convenient building block for the synthesis of (R)-fluoxetine (7a) and (R)-tomoxetine (7b). Compound 1 was converted to the title drugs by etherification with appropriate phenols under Mitsunobu conditions, ozonolysis of the terminal double bond, mesylation of the resulting alcohol and substitution with methylamine.
A stereospecific ruthenium-catalyzed allylic alkylation
Trost, Barry M.,Fraisse, Pierre L.,Ball, Zachary T.
, p. 1059 - 1061 (2007/10/03)
Good regioselectivity and chirality transfer for aryl-substituted allyl units is achieved in allylic alkylations with a wide range of nucleophiles by using the highly active ruthenium catalyst 1. This method provides a route to antidepressants such as (-)-fluoxetine from (S)-ephedrine (see scheme; Cp* = η5-C5Me5, TBAT = tetrabutylammonium triphenyldifluorosilicate).
