(1R)-3-Cyclohexene-1-carboxylic acid Use and Manufacturing

Methods of Manufacturing

Synthesis of Intermediate IV:To a stirred suspension of methylester III (5.19 g, 37.0 mmol) in pH 7.00 phosphate buffer solution (520 ml, 0.07 M), PLE (51.2 mg, 1382 units) was added. The pH was kept at 7 by adding NaOH solution (1.0 M) via syringe pump. The reaction was stirred at r.t. until one equivalent of NaOH (37 ml) was used (11 h, TLC-control: petroleum ether/EtTo a stirred suspension of methylester III (5.19 g, 37.0 mmol) in pH 7.00 phosphate buffer solution (520 ml, 0.07 M), PLE (51.2 mg, 1382 units) was added.

To dissolve the precipitate. The reaction solution was cooled to 50 ° C. and stirred for 2 hours after crystallization. It was gradually cooled to room temperature at 5 ° C / h and stirred for 12 hours. The precipitate was collected by filtration, washed with 2-propanol (10 mL), and dried under reduced pressure at 40 ° C. to obtain the title compound (5.05 g, 50.9percent, 26.5percent ee) as a white solid
