Synthesis of 4-Fluoro-尾-(4-fluorophenyl)-L-phenylalanine by an Asymmetric Phase-Transfer Catalyzed Alkylation: Synthesis on Scale and Catalyst Stability was written by Patterson, Daniel E.;Xie, Shiping;Jones, Lynda A.;Osterhout, Martin H.;Henry, Christopher G.;Roper, Thomas D.. And the article was included in Organic Process Research & Development in 2007.Recommanded Product: (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide This article mentions the following:
4-Fluoro-尾-(4-fluorophenyl)-L-phenylalanine hydrochloride salt was synthesized by the asym. alkylation of tert-Bu glycinate-benzophenone Schiff base using a cinchona alkaloid as a chiral phase transfer catalyst. Upon scaling, it was observed that to achieve high levels of enantioselectivity, it was necessary to add the catalyst or base last. From these studies, insight into the stability of the catalyst under the reaction conditions was gained. In the experiment, the researchers used many compounds, for example, (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide (cas: 200132-54-3Recommanded Product: (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide).
