Novel 2-aminooctahydrocyclopentalene-3a-carboxamides as potent CCR2 antagonists

Novel CCR2 antagonists with a novel 2-aminooctahydrocyclopentalene-3a- carboxamide scaffold were designed. SAR studies led to a series of potent compounds. For example, compound 51 had a good PK profile in both dog and monkey, and exhibited excellent efficacy when dosed orally in an inflammation model in hCCR2 KI mice. In addition, an asymmetric synthesis to the core structures was developed.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Product Details of 624734-17-4. In my other articles, you can also check out more blogs about 624734-17-4

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.624734-17-4,3-Methoxydihydro-2H-pyran-4(3H)-one,as a common compound, the synthetic route is as follows.

624734-17-4, A mixture of the product from Step A (difluoroacetate, 97.45 mg, 0.136 mmol), 3-methoxydihydro-2H-pyran-4(JH)-one (35.4 mg, 0.272 mmol), 4A molecular sieves (60 mg) and TEA (0.19 mL, 1.36 mmol) in DCM (4 mL) was stirred at rt for 2 h, followed by addition of sodium triacetoxyborohydride (46.12 mg, 0.218 mmol). The resulting mixture was stirred at rt overnight. The reaction was quenched by addition of saturated NaHCOs aqueous solution, extracted with DCM, dried over Na2S04. After removal of solvent, the residue was purified by column chromatography (eluent: 5% 7N NH3 in MeOH in DCM) to give the product as a yellow foam. 1H-NMR (400 MHz, CDCI3): delta 1.56 – 2.12 (m, 7 H), 2.31 (br. s., 1 H), 2.55 – 2.67 (m, 1 H), 3.06 – 3.21 (m, 3 H), 3.24 – 4.16 (m, 14 H), 4.71 (br. s., 2 H), 5.12 (s, 2 H), 7.29 – 7.44 (m, 5 H), 7.69 (br. s., 1 H), 8.72 (br. s., 1 H); LC/MS: C3iH37F3N405: m/z 603.0 (M+H).
