With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.180307-56-6,tert-Butyl 4-vinylpiperidine-1-carboxylate,as a common compound, the synthetic route is as follows.
A mixture of 3-sopropoxy-brornobenzene (1.997 g, 1.0 equiv), N-Boc-4- vinylpiperidine (2.943 g, 1.5 equiv), Pd(OAc)? (167 mg, 0.08 equiv), and P(o-tol)3 (680 mg,024 equiv) in CH3CN- Et3N (1:1, 16 mL) was heated at 98 C for 6 h in a sealed vial After cooling to room temperature, the volatiles were removed in vacuo. To the residue, DCM was added, washed with water, brine, dried over Na2SO, filtered, and concentrated. The crude product was purified by column chromatography on silica gel with EtOAc/heptane (0-20%) as an eluent to give 3.1622 g (99%) of Intermediate L as a yellow oil., 180307-56-6
The synthetic route of 180307-56-6 has been constantly updated, and we look forward to future research findings.
