Embodiment 1

[0196] Example 1: (R)-N-((S)-1-(3-chlorophenyl)-2-hydroxyethyl)-2-(2-(2-((1-methyl-1H-pyridine Azol-5-yl)amino)pyridin-4-yl)-4-oxo-4,6-dihydro-5H-thien[2,3-c]pyrrol-5-yl)propionamide

[0197]

[0198] The first step: (4-bromopyridin-2-yl)(1-methyl-1H-pyrazol-5-yl) tert-butyl carbamate (150mg, 0.42mmol), pinacol borate (119mg, 0.47mmol), potassium acetate (123mg, 1.26mmol) and 1,1'-bisdiphenylphosphinoferrocenepalladium dichloride (Pd(dppf)Cl 2 ) (61mg, 0.084mmol) was dissolved in dioxane (10mL), nitrogen was bubbled for 10 minutes, and heated to 80°C for 8 hours under nitrogen protection. The reaction solution was cooled to room temperature, filtered, and concentrated under reduced pressure to obtain (1-methyl-1H-pyrazol-5-yl)(4-(4,4,5,5-tetramethyl-1,3,2- Dioxin-2-yl)pyridin-2-yl)tert-butyl carbamate (yellow oil) was directly used in the next reaction. LC-MS: ESI [M+H]+=401.2; 1 H-NMR(DMSO-d6,400MHz)δ8.34-8.35(m,1H),7.92(s,1H),7.88(s,1H),7.38(d,J=2.0Hz,1H),6.14(d , J=...

Embodiment 2

[0203] Example 2: (R)-N-((S)-1-(3-chlorophenyl)-2-hydroxyethyl)-2-(2-(5-methyl-2-((1-methyl Base-1H-pyrazol-5-yl)amino)pyrimidin-4-yl)-4-oxo-4,6-dihydro-5H-thieno[2,3-c]pyrrol-5-yl)propane Amide

[0204]

[0205] The first step: tert-butyl (R)-2-(4-oxo4,6-dihydro-5H-thieno[2,3-c]pyrrol-5-yl)propionate (1.0g, 3.8 mmol), bispinacol borate (B 2 pin 2 ) (531 mg, 2.1 mmol), 4,4-di-tert-butylbipyridine (dtbpy) (20 mg, 0.076 mmol) and 1,5-cyclooctadiene methoxyiridium [Ir (cod) OMe] 2 ( 25mg, 0.038mmol) was dissolved in tetrahydrofuran (THF) (20mL), replaced with nitrogen for 10 minutes, and heated to 80°C under the protection of nitrogen to react overnight. The reaction solution was cooled to room temperature, filtered, and concentrated under reduced pressure to obtain (R)-2-(4-oxo-2-(4,4,5,5-tetramethyl-1,3,2-dioxin-2 -yl)-4,6-dihydro-5H-thieno[2,3-c]pyrrol-5-yl)propanoic acid tert-butyl ester (1.4g, red oily substance), directly used in the next reaction. LC-MS:ESI[M+H] ...

Embodiment 3

[0210] Example 3: (2R)-N-(2-hydroxyl-1-(m-toluene)ethyl)-2-(2-(5-methyl-2-((1-methyl-1H-pyrazole -5-yl)amino)pyridin-4-yl)-4-oxo-4,6-dihydro-5H-thiophene[2,3-c]pyrrol-5-yl)propionamide

[0211] Example 3 was synthesized by the same method as Example 1, LC-MS: ESI (M+H) 530.5.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and specifically relates to a class of aromatic heterocyclic lactam compounds, a preparation method and application. Background technique [0002] Extracellular signal-regulated kinases (ERKs) are a class of serine / threonine protein kinases discovered in the 1990s and are one of the important subfamilies of the MAPKs family of mitogen-activated protein kinases. Activated ERK can transmit extracellular signals to the nucleus, promote the phosphorylation of cytoplasmic target proteins or regulate the activity of other protein kinases, thereby regulating gene expression. Ras-Raf-MEK-ERK signal transduction is the center of the signaling network involved in regulating cell growth, development and differentiation, so ERK has various biological effects such as regulating cell proliferation, differentiation, migration, invasion and apoptosis. [0003] The Ras / Raf / MEK / ERK pathway is the main signaling...
