139009-66-8, The synthetic route of 139009-66-8 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.139009-66-8,(S)-N-Boc-2,2-dimethyloxazolidine-4-carboxylic Acid,as a common compound, the synthetic route is as follows.

Isobutyl chloroformate (2.51 g; 2.40 mL; 18.36 mmol) and triethylamine (2.25 g; 3.10 mL; 22.24 mmol) were added to a cold (0 C) solution of aminoacetal 2c from the previous step (?3.35 g; 14.27 mmol) in dichloromethane (11 mL) under an argon atmosphere. The reaction mixture was vigorously stirred for 30 min at 0 C, then ethanethiol (2.01 g; 2.40 mL; 32.41 mmol) and triethylamine (2.25 g; 3.10 mL; 22.24 mmol) were added. The resulting solution was stirred for 30 min at 0 C and 45 min at rt. The reaction mixture was diluted with dichloromethane (25 mL), washed with water (40 mL) and brine (30 mL), dried over anhydrous MgSO4, concentrated under reduced pressure and purified by distillation under reduced pressure (bp 110 C/0.3 mmHg) to give 2.19 g (53% over three steps) of thioester 5, as white crystals.
