Methanol → (R)-methyl 2-(tert-butoxycarbonyl)-3-(4-chloro-3-fluorophenyl)propanoate

Participants

Reaction Steps

(Z)-methyl 2-(tert-butoxycarbonyl)-3-(4-chloro-3-fluorophenyl)acrylate (200 mg) and ca. Rh—(R,R)-[Et-DuPhos(COD)]OTf (4 mg) in 1:1 MeOH:EtOAc (3 mL; degassed 1 h with N2 prior to use) was dissolved in 8 Argonaut Endeavor™ reaction tubes. The reaction mixtures were put on the Endeavor™ under 40 psi H2 and stirred for 12 hours at room temperature. All of the reaction mixtures were then combined and concentrated to give (R)-methyl 2-(tert-butoxycarbonyl)-3-(4-chloro-3-fluorophenyl)propanoate (1.52 g, 94.4% yield) as a pale yellow solid, which was used without further purification in next step.
