With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.150407-69-5,(S)-1-((Benzyloxy)carbonyl)-4-(tert-butoxycarbonyl)piperazine-2-carboxylic acid,as a common compound, the synthetic route is as follows.
DIEA (0.3 mL) and HATU (0.63 g) were added to (S)-1-((benzyloxy)carbonyl)-4-(tert-butoxycarbonyl)piperazine-2-carboxylic acid (0.6 g) in DCM (20 mL), and the mixture was stirred for 30 min. Intermediate 1 (1.5 g) was then added, and the mixture was stirred o.n. Volatiles were removed under vacuum evaporated, and the residue taken into EtOAc (60 mL), washed with 0.2% HCl (3×20 mL), sat. NaHC03 (2×15 mL), brine (15 mL), and dried (Na sulfate). Solvent was evaporated under vacuum and the crude product purified by silica gel chromatography (gradient 0-12% MeOH in DCM)., 150407-69-5
150407-69-5 (S)-1-((Benzyloxy)carbonyl)-4-(tert-butoxycarbonyl)piperazine-2-carboxylic acid 1512536, apiperazines compound, is more and more widely used in various fields.
